Question 1

What does kinetic theory say?

Answer 1

That very small particles(like oxygen ) are constantly moving in random directions.They constantly collide with themselves and with the walls of their container.

Question 2

Explain how kinetic energy is proportional to temperature.

Answer 2

Anything that moves has kinetic energy, if you increase the temperature of a gas, you give it’s particle more energy, so they become faster. If you double the absolute temperature you double the average kinetic energy.
