###### Question details

Consider the following P-V diagram showing thermodynamic cycle
for 5 moles of an ideal monatomic gas.

A. For eah segment of the cycle, determine if the following
quantities are positive, negative, or zero: Q added to the system,
W done by the system, and (delta)Eth (the change in internal energy
of the system). Include a short reason with each answer for full
credit.

B. This PV diagram actually describes one full cycle of a heat
engine. Given that Eb - Ec = 1000J and Pd = 1.5Pc, determine if tis
efficiency is equal to the theoretical maximum. Show all work for
full credit.
