Key Concepts

Kinetic Molecular Theory

This theory explains that gas pressure is due to the collisions of gas molecules with the walls of their container. Under constant temperature, the kinetic energy of the molecules remains constant, but an increased number of molecules per unit volume leads to more frequent collisions, hence increasing the pressure.

Collision Frequency

When a gas is compressed into a smaller volume while keeping the temperature constant, the molecules have less space to move, causing them to collide with the container walls more frequently. This higher rate of collisions per unit area is the primary reason for the increase in pressure.

Pressure

Pressure in a gas is defined as the force exerted per unit area by the molecules during their collisions with the container walls. An increase in the frequency of these collisions, without a change in the speed or kinetic energy of the molecules, results in an increase in the overall pressure.
