The ideal gas law relates which three variables?

The ideal gas law describes the relationship between pressure, volume, and temperature in a gas. This relationship is articulated through the equation PV = nRT, where P represents pressure, V represents volume, T represents temperature, n is the number of moles of gas, and R is the ideal gas constant. In this framework, if you know any two of the variables (pressure, volume, or temperature), you can calculate the third, assuming the gas behaves ideally.

This law is a critical foundation in both chemistry and physics, providing insight into how gases behave under varying conditions. For example, increasing the temperature of a gas while holding the volume constant will increase the pressure. Conversely, if the volume is increased while keeping the temperature constant, the pressure will decrease. Understanding these relationships is essential for explaining various phenomena, including weather patterns, engine efficiency, and the behavior of gases in different scientific applications.
