The kinetic theory of gases leads to the derivation of the ideal gas law. Indicate TWO things in the list below that we learn from the kinetic theory.

Group of answer choices

A. The pressure of a gas comes from the force of the collisions of gas particles with the container walls.

B. The temperature of a gas (in Kelvins) is proportional to the average kinetic energy of the gas molecules.

C. Molecules in a gas slow down as the temperature increases.

D. All the molecules in a gas travel at the same speed, at a given temperature.
