13.10 Kinetic Theory and Temperature Assumptions: • 1. The number of molecules in the gas is large and they are far apart. • 2. The molecules obey Newton’s laws of motion but move randomly. • 3. The molecules interact only by short-range forces during elastic collisions. • 4. The molecules make elastic collisions with container walls. • 5. The gas is pure – all molecules are identical APHY201
