Example problem 2.2 1.00 mole of an ideal gas (the system) is confined in a piston and cylinder assembly similar to that shown in figure on right. The piston radius is 10.0 cm, and the total mass on the weightless piston is 64.0 kg. The initial temperature is 300. K. The gas is irreversibly expanded at constant temperature by removing half of the mass. The surroundings are evacuated. a. Describe in words the evolution of the system when the mass on the piston is reduced. b. Calculate w for this irreversible process using Wrev comp = -√ Pdv. c. Calculate w for this process using w=-Wsur = -mgAh Compare your result with your results for part (b) Mechanical Peton AV Ma
