Student: Mary Chrisin L. ObreroDate: October 7‚ 2014 Section: 116 Behavior of Gases and Determination of Absolute Zero Experiments 4&5 Introduction: First of all‚ the Boyle’s law (pressure-volume law) indicates that the volume of a certain amount of gas given held at a constant temperature differentiates inversely with the applied pressure when there are constant temperature and mass. Equations: PV=C. When pressure goes up‚ volume goes down (derived from the equation above): P1V1 = P2V2 =

The purpose of this experiment is to discover the physical and chemical properties of the studied gases. In discovering these properties it allows the student or observer the ability to identify these gases when they come into contact with them. Procedure Before I began the procedure I gathered all my supplies from the given list in the manual. From there I began the actual experiment and diluted the HCL placed in a test tube and then placed the ZN in the tube as well. I placed the stopper

What are Greenhouse Gases? These are the gases that make up our atmosphere: Carbon Dioxide 89% Methane 7% Nitrous Oxide 3% Halocarbons 1% What is the Greenhouse Effect? The Greenhouse Effect is the way that gases in the atmosphere trap heat from the sun. They let heat in‚ but prevent most of it from escaping. It is essential for life because we need a certain amount of radiation to heat up our atmosphere. What human activities produce Greenhouse Gases? By burning fossil fuels such as coal‚ oil and

Poisonous gases changed the experiences of the people in the war for the worse. Breaking on impact‚ the canisters released yellowish green fumes that wafted slowly toward the French and African troops near the Belgian town of Ypres. As the fumes reached the Allied forces‚ soldiers realized the cloud was poisonous chlorine gas. Quoted in Dooly’s Great Weapons of World War I‚ one French doctor at Ypres expressed his horror: “I had the impression that was looking through green glasses. At the same time
