Explanation: At constant pressure, Charles's law states that the volume of a given amount of gas is directly proportional to its temperature on the kelvin scale. [0 Kelvin = 0 Liters gas]
. Charles’s law—named for J.-A.-C. Charles (1746–1823)—states that, at constant pressure, the volume V of a gas is directly proportional to its absolute (Kelvin) temperature T, or V/T = k.
