# 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 vol-ume of the system if the internal energy of the system Decreased by 102.5 J?
