Which law demonstrates how gases respond consistently with temperature changes?

The law that demonstrates how gases respond consistently with temperature changes is Charles's Law. This law states that at constant pressure, the volume of a gas is directly proportional to its absolute temperature (measured in Kelvin). This means that as the temperature of a gas increases, its volume also increases, provided the pressure remains constant.

This relationship can be observed practically: for example, when a balloon is heated, the increased temperature causes the gas molecules inside to move more vigorously, leading to an expansion of the volume of the balloon. This consistent behavior under various temperature conditions is a key feature of Charles's Law and is critical for understanding gas behavior in various applications, such as in industrial processes and scientific experiments.

Other laws mentioned pertain to different gas behaviors; Boyle's Law focuses on the inverse relationship between volume and pressure at constant temperature. Avogadro's Law relates the volume of gas to the number of gas molecules at constant temperature and pressure. Dalton's Law addresses the partial pressures of gases in a mixture. Each of these laws is important in the study of gases but does not directly address the relationship between temperature and volume as Charles's Law does.
