in calorimetry, the heat released by the system is equal to the heat absorbed by its surrounding.…
* Remember that temperature is a measure of the average kinetic energy of the particles in a substance. This means that the addition of heat to a solid causes the vibration of the particles to increase more and more as the temperature of the solid increases. This increase in vibration will continue until, at a certain temperature, the vibrations are rapid enough to break up the fixed arrangement of particles. At this point a solid will begin to melt into a liquid.…

The Ideal Gas Law demonstrates the relationship of the properties of gases. This relationship is specific to the gases that are considered “ideal”. For a gas to be considered “ideal,” it will have no interactions with other molecules and the molecules that make up the gas won’t take up any space.…

Few historical events were as gut-wrenchingly horrifying as the Holocaust. It inspired countless stories in the decades that followed it. One example, Frank Borowski's “This Way for the Gas, Ladies and Gentlemen,” is a saddening story about a man working at the Auschwitz-Birkenau concentration camp during World War II. It details his experiences collecting the belongings of prisoners who arrived at the camp, and his interactions with another worker. A large portion of the text had the narrator describing various specific prisoners, and thinking about how they affect him. This section presented an ironic incompatibility between two outlooks that is worthy of analysis, and provided indication as to Borowski’s intent for writing the story.…

The two stories that I am comparing and contrasting are “How to Tell a True War Story” by Tim O’Brien. Also, “This Way for the Gas, Ladies and Gentlemen” by Borowski, Both stories contains vivid imagery of happenings during the German and Vietnam War. Also the two stories both share a similar theme which is war, yet there faced with two different obstacles during the war. The United States and Poland both suffered hardships watching their countries being torn apart and innocent lives taken. For a reason that no one has the answer too, but will always remember those moments. I picked these novels because just by reading the title I know that each novel is about a War that had a dramatic impact on the world. So the two…

It is finally Friday! When I walked out of the house, my ears immediately froze. I noticed the frost covering the lawns and roofs of the houses in the neighborhood. The frost made it blatantly obvious that today’s walk would be very cold. Meera walked with a twin shirt and one jacket, then immediately rushed back into the house to layer my coats. In history, Mr. Martell announced that we would be doing a group project. My group is pretty good, and the people usually don’t make blunders, so we should be fine. Mr. Penner gave us two gas laws worksheets, both were pretty hard thinking problems. He said these worksheets would bolster our problem solving skills. The questions were a bit bewildering at first, but I gradually figured them out. We…

Energy is encountered in many forms, such as mechanical, chemical (food and fuel), electrical, nuclear, heat, and radiant (light). Energy has the ability to bring about change or to do work. Thermodynamics is the study of energy. The field of thermodynamics studies the behavior of energy flow in natural systems. These studies have rendered two laws of thermodynamics.…
