Exercise: Cyclic Process
Exercise:
Cyclic Process
A
thermodynamic system undergoes a cycle composed of a series of three processes
for which Q1 = +10 kJ, Q2 = +30 kJ, and
Q3 = -5 kJ. For the first process, \( \Delta \)U = +20 kJ, and for the third process, \( \Delta \)U = -20 kJ. What is the work in the
second process, and the net work output of the cycle?
