For a gas, temperature and volume are directly proportional. Keeping everything else constant, as the temperature of a gas goes up, its volume goes up. As the temperature of a gas goes down, its volume goes down.
Charles’s Law says that for a given amount of gas, at fixed pressure, volume and temperature are directly proportional.
You can write this mathematically as
V ∝ T or V = kT, where k is a proportionality constant
