As a system amplifies in volume it absorbs 52.5 J of energy in the form of heat from the surroundings. The piston is working against a pressure of 0.500 atm. The final volume of the system is 58.0 L. Explain what was the initial volume of the system if the internal energy of the system decreased by 102.2 J?
