According to Charles's Law, what happens to the volume of a gas when temperature increases, provided pressure remains unchanged?

According to Charles's Law, when the temperature of a gas increases while the pressure remains constant, the volume of the gas increases. This relationship reveals that gas volume is directly proportional to its absolute temperature, measured in Kelvin. The basic principle behind this law is that as the temperature rises, the kinetic energy of the gas molecules increases, causing them to move more rapidly. This increased movement leads to a greater distance between the molecules, resulting in an expansion of the gas volume.

In practical terms, if you take a balloon and heat it, for instance, the air inside expands as the temperature rises, causing the balloon to inflate. This showcases how, under constant pressure, the gas readily adapts to changes in temperature by increasing its volume.
