Question

The main assumptions of the Kinetic Molecular Theory of gases are: 1. Gases are made up of molecules which are relatively far apart. 2. The molecules are in motion at high speeds. 3. The molecules are perfectly elastic. 4. Increase in temperature increases the kinetic energy of the molecules. The assumption that explains the pressure a gas exerts is:
1
2
3
4
none

Answer 1

2

Answer 2

speed - momentum- change in momentum after colliding - force - gaseous pressure
