Learn what Charles 's law states, how it relates to the motion of gas particles and temperature, and how it is used to explain hot air balloons, tires and automobiles. Find out the equation, formula and examples of Charles 's law and its inverse. What Is Charle’s Law ? Charles ’s Law , also known as the law of volumes, is a gas law that describes how gases tend to expand when heated. It states that, at constant pressure, the volume of a given mass of gas is directly proportional to its absolute temperature. Mathematically, Charles ’s Law is expressed as: Charle’s Law Formula V 1 / T 1 = V 2 / T 2 where: V 1 and V 2 are the initial and final volumes of the gas, T 1 and T 2 are the initial and final absolute temperatures of the gas ... Charle’s Law Charles' Law is a key principle in thermodynamics that explains how gases expand when heated and contract when cooled, at constant pressure. Named after French scientist Jacques Charles, the law states that the volume of a gas is directly related to its temperature. Charles’s law , a statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant. This empirical relation was first suggested by the French physicist J.-A.-C. Charles about 1787.
