Using the kinetic molecular theory, explain what the difference is between a gas that exerts a pressure of 1.0 atm and one that exerts a pressure of 1.5 atm

A gas with more kinetic energy exerts more pressure.

Explanation:

A gas that has more kinetic energy has faster particles movement. When these molecules move at a faster speed, they exert more pressure on the surface with which they collide.

Here, molecular speed of gas that exerts 1.0 atm of pressure is less than that which exerts 1.5 atm of pressure.

Kinetic molecular theory states that molecules in a gas are continuously in motion show elastic collisions.

The pressure exerted by a gas is directly proportional to the  mean-square velocity of gas molecules.
