    Calculating Entropy Change in an expansion

    The units are 0.34 J/K and as for the moles I think we were to assume the gas to be one mole.

    Calculating Entropy Change in an expansion

    1. Suppose that you have a sample of a gas in a cylinder equipped with a piston that has a volume of 1.50 L, a pressure of 1.20 atm, and a temperature of 250 K. Suppose that the gas is expanded reversibility under isothermal conditions until the pressure is 0.75 atm. What is the entropy change...
