Key Concepts

Kinetic Molecular Theory

This theory explains that gas pressure arises from the collisions of molecules with the walls of a container. As the temperature increases, the molecules move faster, resulting in more frequent and forceful collisions, which in turn increases the pressure of the gas.

Ideal Gas Law

The ideal gas law (PV = nRT) relates the pressure, volume, temperature, and amount of a gas. Under conditions of constant volume and a fixed number of moles, an increase in temperature leads directly to an increase in pressure, as the product of nRT must be accommodated by an equivalent rise in pressure.
