Which equation relates pressure, volume, and temperature of a gas?

The General Gas Equation, also known as the Ideal Gas Law, is the relationship that incorporates pressure, volume, temperature, and the number of moles of a gas. It is represented by the equation PV = nRT, where P stands for pressure, V for volume, n for the number of moles, R is the ideal gas constant, and T is the absolute temperature in Kelvin. This equation is significant because it summarizes the behavior of an ideal gas under various conditions, making it a foundational concept in thermodynamics and fluid mechanics.

Boyle's Law and Charles' Law, while important, describe specific relationships under certain conditions instead of a comprehensive equation. Boyle's Law focuses on the inverse relationship between pressure and volume at constant temperature, while Charles' Law highlights the direct relationship between volume and temperature at constant pressure. The Specific Heat Capacity Equation pertains to heat transfer and does not directly relate to pressure, volume, and temperature. Thus, the General Gas Equation is the correct choice as it provides a complete analysis of how these variables interact in a gas.
