Gases Our fundamental understanding of"ideal gases makes the following 4 assumptions. Describe how each of these assumptions is (or is not!) represented in the simulation. Assumption of KMT Representation in Simulation 1. Gas particles are separated by relatively large distances. 2. Gas molecules are constantly in random motion and undergo elastic collisions (like billiard balls) with each other and the walls of the container 3. Gas molecules are not attracted or repulsed by each other 4. The average kinetic energy of gas molecules in a sample is proportional to temperature (in K). 245 CHEM10 - Laboratory Manual/Lab 19
