Calculate the internal energy change for each of the following. a. One hundred (100.) joules of work is required to compress a gas. At the same time, the gas releases 57

J of heat. Internal energy change = J b. A piston is compressed from a volume of 7.90 L to 7.75 L against a constant pressure of 2.85 atm. In the process, there is a heat gain by the system of 764 J. Internal energy change = J c. A piston expands against 1.10 atm of pressure from 16.3 L to 27.9 L. In the process, 1182 J of heat is absorbed.
