According to Boyle's law, what does the letter 'V' represent?

Boyle's law describes the relationship between the pressure and volume of a gas at constant temperature. It specifically states that for a given amount of gas, at constant temperature, the pressure of the gas is inversely proportional to its volume. In this context, 'V' represents Volume, which quantifies the space the gas occupies. The formula of Boyle's law is often expressed as P1V1 = P2V2, indicating that when the volume (V) of a gas increases, the pressure (P) decreases, provided the temperature remains unchanged. Understanding that 'V' is the volume helps to clarify how changes in the volume of a gas will affect its pressure under fixed temperature conditions.
