when you need more precision. There are other models for real gases. One model gives the equation of state as N²o (P + №²a) (v (V-NB) = KT V2 where a and 3 are constants that depend on the molecules that make up the gas (specifically, a is related to the electrostatic interactions between molecules, and ß is related to the size of a molecule). Determine the work done by this gas on its surroundings as it expands from an initial volume Vo to a final volume 3V at a constant temperature To. Your result will be in terms of Vo, To, N, and constants.
