calculate the internal energy change for each of the following.
a. one hundred(100.)joules of work are required to compress a gas. at the same time the gas releases 23 J of heat.
b. a piston is compressed from a volume of 8.30 L to 2.80 L against a constant pressure of 1.90 atm. in the process, there is a heat gain by the system of 350. J.
c. a piston expands against 1.00 atm of pressure from 11.2 L to 29.1 L. in the process, 1037 J of heat is absorbed.

delta E = delta H + w and w = -P*delta V.
