Boyle’s Law states that the product of pressure and volume for a gas is constant when temperature and the amount of gas remain unchanged. Charles’s Law states that the volume of a gas is directly proportional to its temperature at constant pressure and quantity of gas. Both laws describe gas behavior under varying conditions.
