Charles Law Application in Real Life Charles Law Solved Problems What Is Charles Law ? Charles’ law , also sometimes referred to as the law of volumes, gives a detailed account of how gas expands when the temperature is increased. Conversely, when there is a decrease in temperature, it will lead to a decrease in volume. Learn how Charles ' law describes the relationship between temperature and volume of a gas at constant pressure. See the equation, graph, and everyday applications of this gas law , and solve some problems with solutions. 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. 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.
