Is Air Made of Matter

Is air made of matter? To fit into the standard definition of matter in science, air must have mass and it must take up space. You cant see or smell the air, so you may be wondering about its status. Matter is physical material, and it is the fundamental element in all of us, all of life, and all of the universe. But...air? Yes, air does have mass and does take up physical space, so, yes, air is made of  matter. Proving Air Is Matter One way to prove that air is made of matter is to blow up a balloon. Before you add air into the balloon, it is empty and shapeless. When you puff air into it, the balloon expands, so you know it is filled with something—air is taking up the space. Youll also notice that a balloon filled with air sinks to the ground. Thats because compressed air is heavier than its surroundings, so the air has mass or weight. Consider the ways you experience air. You can feel the wind and see that it exerts a force on the leaves on trees or a kite. Pressure is mass per unit volume, so if there is pressure, you know the air must have mass. If you have access to the equipment, you can weigh air. You need a vacuum pump and either a large volume of air or a sensitive scale. Weigh a container filled with air, then use the pump to remove the air. Weigh the container again and note the decrease in weight. That proves something that had mass was removed from the container. Also, you know the air you removed was taking up space. Therefore, air fits the definition of matter. Air is quite important matter, in fact. The matter in the air is what supports the enormous weight of a plane. It also holds clouds aloft. The average cloud weighs about a million pounds. If there were nothing between a cloud and the ground, it would fall. What Type of Matter Is Air? Air is an example of the type of matter known as gas. Other common forms of matter are solids and liquids. Gas is a form of matter that can change its shape and volume. Considering the air-filled balloon, you know you can squeeze the balloon to change its shape. You can compress a balloon to force the air into a smaller volume, and when you pop the balloon, the air expands to fill a larger volume. If you analyze air, it consists mostly of nitrogen and oxygen, with smaller amounts of several other gases, including argon, carbon dioxide, and neon. Water vapor is another important component of air. The Amount of Matter in Air Isnt Constant The amount of matter in a sample of air isnt constant from one place to another. The density of air depends on temperature and altitude. A liter of air from sea level contains many more gas particles than a liter of air from a mountaintop, which in turn would contain much more matter than a liter of air from the stratosphere. Air is most dense close to the surface of the Earth. At sea level, there is a large column of air pushing down on the surface, compressing the gas at the bottom and giving it a higher density and pressure. Its like diving into a pool and feeling the pressure increase as you go deeper into the water, except liquid water doesnt compress nearly as readily as gaseous air. While you cant see or taste the air, that is because as a gas, its particles are very far apart. When air is condensed into its liquid form, it becomes visible. It still doesnt have a flavor (not that you could taste liquid air without getting frostbite). Using human senses isnt a definitive test for whether something is matter or not. For example, you can see light, yet its energy and not matter. Unlike light, air has mass and takes up space. Resources and Further Reading Butcher, Samuel and Robert J. Charlson.

Why Is A New Environmental Assessment Regime Necessary

1. Why is a new environmental assessment regime necessary? What prompted the goals outlined in the Liberal platform and the subsequent environmental assessment review? Ever since the creation of the National Energy Board, the idea of an environmental assessment regime has been necessary to accommodate the different types of environmental projects and concerns that appear over the years. An environmental government signifies a new set of regulations and mechanisms for impacts to be analyzed at the state and provincial level. From then onwards, many advocates of environmental change have identified that communities and local groups should be part of the governance process. This is why public private partnerships and public consultation are formed. Moreover, a new environment regime allows for a quicker implementation of projects. As the public input from the community and other interested parties would be less inclined to challenge any proposal that benefits them. Perhaps the most important part of why a new environmental regime is vital is to anticipate the adverse risks of climate change. In the North American context, the origins of EIA has been dated back to the 1960’s where environmental awareness and the public was upset in the USA. The National Environmental Policy Act that was developed in 1969 was one of the first forms of legislated that was a form of EIA (Wall, 2016).

Beowulf a Heroic-Elegiac Poem Free Essays

Beowulf: A Heroic Elegiac Poem Beowulf is definitely a heroic-elegiac poem. Beowulf was a hero to many. He exhibited, the traits of a â€Å"good king†. We will write a custom essay sample on Beowulf: a Heroic-Elegiac Poem or any similar topic only for you Order Now He was a warrior with extraordinary abilities which made him seem superhuman. He was selfless choosing to protect the masses rather than himself. This was an act of generosity, as well as, great loyalty. There are many references in the poem to the ancestors of both Beowulf and Hrothgar. They are referred to with reverence regardless to whether they were good or bad. The references are made as lessons to the present and future kings and queens. As a heroic-elegiac poem, Beowulf begins with an example of a bad king to contrast him with a good king. Shield Sheafson who was not a good king because he demanded that clans far and wide pay homage to him. He destroyed mead halls and rampaged through the countryside. He was selfish and cruel. His heir, Beow, would be the antithesis of his father. He would be a blessing to the Danes. Beow would be known for his generosity which garnered him loyal followers. Beow was the grandfather of Hrothgar. Hrothgar was loyal, courageous, generous and protective of his kingdom. Hrothgar was a good king like his father and grandfather before him. He would decide to build a mead hall where he could share his treasures and good fortune with his people, a place where they could feast and rejoice. These events described here prove that, in fact, Beowulf is a heroic poem. The mead hall, Heorot, would only be a safe haven for a short while. The hall would come under attack. Grendel, a monster, would be annoyed by the sounds of gaiety day in and day out. Grendel would begin to terrorize the hall murdering many before the would be abandoned due to fear. Hrothgar kingdom was gripped in terror. Beowulf heard of Hrothgar’s plight and decided he needed his help. Beowulf was known to have the strength of thirty men in each arm. He would travel to Hrothgar’s kingdom to volunteer to be their defender against Grendel. He demonstrated selflessness, courage and generosity for the people of another land. All these are attributes of a good king and hero as shown in the poem. The transitory state of human relationships is shown in the repeated conquests of Beowulf. Beowulf killed Grendel and then he would have to kill Grendel’s mother who was seeking revenge for her child’s death. He was rewarded many times over by Hrothgar and he shared his good fortune with his men. Hrothgar offered him the throne. Beowulf declined in deference to the rightful heirs. Beowulf, eventually, becomes the king of the Geats. â€Å"He ruled (it) well for fifty winters, grew old and wise as warden of the land. † He is tested for a final time. His kingdom is threatened by a dragon. Beowulf challenges the dragon alone and he is mortally wounded. Wiglaf was the only warrior to remain by his side. Wiglaf stated, â€Å"Anyone ready to admit the truth will surely realize that the lord of men who showered you with gifts and gave you he armor you are standing in—when he would distribute helmets and mail-shirts to men on the mead-benches, a prince treating his thanes in the hall to the best he could find, far or near—was throwing weapons uselessly away. It would be a sad waste when the war broke out. Beowulf had little cause to brag about his armed guard; yet God who ord ains who wins or loses allowed him to strike with his own blade when bravery was needed. There was little I could do to protect his life in the heat of the fray, but I found new strength welling up when I went to help him. Then my sword connected and the deadly assaults of our foe grew weaker, the fire coursed less strongly from his head. But when the worst happened too few rallied around the prince. So it is good-bye now to all you know and love on your home ground, the open-handedness, the giving of war- swords. Every one of you with freehold of land, our whole nation, will be dispossessed, once princes from beyond get tidings of how you turned and fled and disgraced yourselves. A warrior will sooner die than live a life of shame. † This excerpt from the poem shows the transitory state of human relationships proving Beowulf is an elegiac poem.

Empathy in the Film Beneath Hill 60 Essay Example For Students

Empathy in the Film Beneath Hill 60 Essay In film, the emotion of empathy has the power to draw the audience further into the plot of the story. Using specific techniques to create empathy, we often notice that the movie will touch more hearts worldwide. The director of the film Beneath Hill 60 has used film techniques to ensure that the audience becomes attached to each character in a certain way. The way empathy is portrayed in this movie is by flashbacks, love and romance, death situations, and age. Woodward, also known as Woody, is the main character of this film. Throughout the text, the producers use film techniques to draw empathy from the audience towards the character. The main technique used periodically throughout the film is the flashbacks from Woodward’s past just before he signed up for the war. The producers create flashbacks to show Woodward and Marjorie’s journey of slowly falling in love with one another. Love is what brings the audience wanting Woodward to make it back from war so he can be with his soul mate. This brings the audience closer towards both, as they would be empathetic towards the situation given as there is no guarantee that Woodward would make it back home from war. Each flashback that the producers and scriptwriters from ‘Beneath Hill 60 show us is the couples love story from the start to the end. We as an audience get to see, and become attached, to how in love the two characters are. In this film text Woodward’s flashbacks show that he asks Marjorie’s father if he has permission to send letters to her. We see in this movie that he sends a jewellery box to her as a gift, made by his fellow soldier, Tiffin. This jewellery appears another two times in the movie, at the start and at the end. This jewellery box is symbolic of the horrors of war, and Tiffin trying to still find light and further his hobby in carpentry by giving his captain, Woody, a gift for his lady. Woodward was the captain of all the miners who had also enlisted into the war, and he met Tiffin at the very start. Tiffin was a young 16 year old who was not ready to join the war. As the story of the film progresses the producers use film techniques to make us feel sympathy for Tiffin. One major technique and scene in this text was when Tiffin was left behind towards the end, in a small, dark, cramped tunnel underground. He didnt have much time, and couldve been saved. The audience was made to feel attached to him at that specific moment, as the filmmakers showed him sitting there, waiting to be saved. As they were showing this, they also had Woodward sitting in the trench waiting to pull the trigger to set off the explosion that ended the war at Hill 60, while also being given an ultimatum. He knew Tiffin was down there, and had time to go and save him, but he also could not as he had everyone else’s lives on his hands. Who knew what wouldve happened if he did not pull the trigger as planned? This is the one film technique that made a massive impact on the audience as they are left with the unknown. At the end of the film there is one other major technique used, and that was when the miners had gotten back from the war and were having their picture taken. Woodward picks up the jewellery box and stares at it in remembrance of Tiffin. The viewers also notice that while the picture is being taken a fellow miner/soldier that has been traumatised from the war break down as he keeps checking for bombs and gunshots. This then makes the audience feel empathetic for him and all the soldiers who had fought in the war, as it is a horrible thing that no person should ever of had to face. .ud460707d9ec7e2bac72ebd5ff930c4d4 , .ud460707d9ec7e2bac72ebd5ff930c4d4 .postImageUrl , .ud460707d9ec7e2bac72ebd5ff930c4d4 .centered-text-area { min-height: 80px; position: relative; } .ud460707d9ec7e2bac72ebd5ff930c4d4 , .ud460707d9ec7e2bac72ebd5ff930c4d4:hover , .ud460707d9ec7e2bac72ebd5ff930c4d4:visited , .ud460707d9ec7e2bac72ebd5ff930c4d4:active { border:0!important; } .ud460707d9ec7e2bac72ebd5ff930c4d4 .clearfix:after { content: ""; display: table; clear: both; } .ud460707d9ec7e2bac72ebd5ff930c4d4 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ud460707d9ec7e2bac72ebd5ff930c4d4:active , .ud460707d9ec7e2bac72ebd5ff930c4d4:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ud460707d9ec7e2bac72ebd5ff930c4d4 .centered-text-area { width: 100%; position: relative ; } .ud460707d9ec7e2bac72ebd5ff930c4d4 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ud460707d9ec7e2bac72ebd5ff930c4d4 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ud460707d9ec7e2bac72ebd5ff930c4d4 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ud460707d9ec7e2bac72ebd5ff930c4d4:hover .ctaButton { background-color: #34495E!important; } .ud460707d9ec7e2bac72ebd5ff930c4d4 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ud460707d9ec7e2bac72ebd5ff930c4d4 .ud460707d9ec7e2bac72ebd5ff930c4d4-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ud460707d9ec7e2bac72ebd5ff930c4d4:after { content: ""; display: block; clear: both; } READ: O Brother Where Art Thou?
