Ideal Gas Equation  

The ideal gas equation is one that combines four variables into one equation. The ideal gas equation considers pressure, temperature, volume, and the number of particles. The law is stated as:  PV = nRT. R is a gas constant and has the value of 0.83. n is the number of molecules. P is pressure, V is volume, and T is Kelvin temperature. By knowing the value of three of the variables plus the value of R, you can calculate the value of the fourth variable.
