Question

As a system increases 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. What was the initial volume of the system if the internal energy of the system decreased by 102.5 J? (1 L-atm = 101.3 J)
