Charles's Law is a fundamental principle in thermodynamics that explains the direct relationship between the temperature and volume of a gas when pressure remains constant.

The volume of a gas is directly proportional to its temperature, provided the pressure remains constant. In simple terms, as the temperature of a gas increases, its volume also increases, and vice versa.

This relationship is captured in the formula:

$\frac{V_1}{T_1} = \frac{V_2}{T_2}$

Where:

• ${V_1}$ and ${V_2}$ represent the initial and final volumes of the gas.
• ${T_1}$ and ${T_2}$ are the initial and final temperatures in Kelvin.
