What happens to the gas volume when temperature increases, according to Charles' Law?

According to Charles' Law, when the temperature of a gas increases, its volume also increases, provided the pressure remains constant. This law is rooted in the kinetic theory of gases, which states that as the temperature rises, the kinetic energy of the gas molecules also increases. Consequently, the molecules move more vigorously and tend to occupy a larger space.

Thus, if you heat a gas, its volume will expand as the temperature rises. This relationship demonstrates a direct proportionality between volume and temperature, affirming that at higher temperatures, gases expand if the pressure conditions do not change.
