What is the equation for the ideal gas law?

The ideal gas law is a fundamental equation in chemistry that describes the relationship between the pressure, volume, temperature, and number of moles of an ideal gas. The correct equation captures this relationship perfectly as PV = nRT. In this equation:

• P represents the pressure of the gas,

• V denotes the volume the gas occupies,

• n is the number of moles of the gas,

• R is the universal gas constant, and

• T is the absolute temperature measured in Kelvin.

This equation demonstrates how, for an ideal gas, the product of pressure and volume is proportional to the product of the number of moles and the absolute temperature, with R acting as the proportionality constant specific to the units of the variables involved. Understanding this equation is crucial as it allows for calculations involving different properties of gases and is foundational in both physical chemistry and thermodynamics.
