Question
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 43 J
of heat.
Internal energy change =
J
b. A piston is compressed from a volume of 8.65 L to
1.55 L against a constant pressure of 4.20 atm. In the
process, there is a heat gain by the system of 524 J.
Internal energy change =
J
c. A piston expands against 1.30 atm of pressure from
35.0 L to 45.5 L. In the process, 1759 J of heat is
absorbed.
Internal energy change =
J
