16 Characteristics of a Gas Page 17 Pictures of Gases Page 18 Q & A Page 19 Bibliography Page 20 Kinetic Theory of Molecules The kinetic theory of molecules describes the behavior of matter in terms of particles in motion. This theory makes these assumptions: 1. Gases are made up of particles with no defined volume but with a defined mass. In other words their volume is miniscule compared to the distance between themselves and other molecules. 2. Gas particles undergo no intermolecular

experiment was to calculate the heat capacity ratio γ for three gases find in three different classes. The three different gases and their classes are; helium which is classified as a monatomic gas‚ nitrogen which is classified as a diatomic gas and carbon dioxide‚ which is classified as a linear triatomic gas. After these experimental heat capacities ratio were calculated they were then compared with theoretical values. Introduction: Heat capacity is a very important concept in thermodynamics. It

Collecting Butane Gas The purpose of the lab was to determine the molecular mass of Butane‚ and this was done by using the ideal gas law (PV=nRT). The materials used were: match‚ funnel‚ bucket‚ cylinder‚ thermometer‚ lighter‚ scale‚ and a wooden flynt. These materials are used to help collect and test the Butane gas. Butane gas was used because it is ideal at standard temperature and pressure. Procedure: 1. Rinse bucket and fill three fourths full. 2. Rinse all glassware. 3. Place
