ChemistryFor 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
