Charles’ Law describes the relationship between the volume and temperature of a gas at constant pressure. According to Charles’ Law, the volume of a gas is directly proportional to its temperature when the pressure is held constant. This means that as the temperature of a gas increases, its volume also increases, and as the temperature decreases, the volume decreases.
Mathematically, Charles’ Law can be expressed as:
V ∝ T
or
V = kT
where:
- V is the volume of the gas
- T is the temperature of the gas (in Kelvin)
- k is a constant
This relationship is crucial in understanding how gases behave under different temperature conditions and is widely used in various scientific and engineering applications.
