Which equation represents the Ideal Gas Law?

The Ideal Gas Law describes the relationship between pressure, volume, temperature, and the number of moles of a gas. The equation that encapsulates these variables is PV = nRT. In this equation, P represents the pressure of the gas, V is the volume it occupies, n is the number of moles of gas, R is the universal gas constant, and T is the absolute temperature measured in Kelvin.

This equation is fundamental in understanding the behavior of ideal gases, as it shows how these properties interact with one another. For example, if the volume of a gas increases while the number of moles and temperature remain constant, the pressure must decrease, illustrating the inverse relationship between volume and pressure.

The other choices do not accurately represent the Ideal Gas Law in its complete form. While they may represent certain relationships between the variables or specific alterations of the law, they do not encompass the comprehensive relationship that the Ideal Gas Law demonstrates as clearly as PV = nRT does.
