An ideal gas is confined to a container with adjustable volume. The pressure and mole number are constant. By what factor will volume change if absolute temperature triples

Charles' Law describes the relationship between temperature and volume of a gas. The law states that a fixed amount of gas at a fixed pressure will have a volume directly proportional to the absolute temperature of the gas. This law was formulated on the basis of experimental observations.
