Boyle's law states that, at a constant temperature, the volume of a given mass of gas varies inversely with pressure. ... Thus Charles's law states that at a constant pressure, the volume of a given mass of gas is directly proportional to its (absolute)temperature.
The volume of a fixed mass of gas is directly proportional to its Kelvin temperatureif the pressure is kept constant. ... The pressure of a gas is directly proportional to its Kelvin temperature if the volume is kept constant.
