Gases: Gases: Behavior Quiz

Substances that are gases at room temperature display similar physical properties despite their composition. The Kinetic Molecular Theory is a model that explains the behavior of gases in terms of particles in motion. Several assumptions are made: 1. Gases consist of small particles; 2. Gas particles are in constant, random motion, and 3. Gases are measured in terms of kinetic energy, or temperature. Kinetic energy uses one-half of the mass of a particle times its velocity squared. Using this information as a reference, answer the following questions. Select the best answer from the choices.
