What is Charles' Law primarily concerned with?

Charles' Law is a fundamental principle in gas physics that specifically addresses the relationship between the volume and temperature of a gas at constant pressure. According to Charles' Law, when the temperature of a gas increases, its volume increases, provided the pressure remains unchanged. This relationship can be articulated mathematically as V1/T1 = V2/T2, where V represents volume and T represents temperature in Kelvin. This law illustrates the direct proportionality between temperature and volume; as one increases, the other does as well.

By focusing exclusively on the interplay between volume and temperature, Charles' Law lays the groundwork for understanding how gases behave under varying thermal conditions, making it essential in both scientific and practical applications involving gases.
