Question: the ammonia increases by ( 2 5 % ) , while its pressure varies negligibly. Determine, in Btu, a . the amount

the ammonia increases by \(25\%\), while its pressure varies negligibly. Determine, in Btu,
a. the amount of energy transfer by electrical work and the accompanying exergy transfer.
b. the amount of energy transfer by work to the piston and the accompanying exergy transfer.
c. the change in exergy of the ammonia.
d. the amount of exergy destruction.
Ignore the effects of motion and gravity and let \( T_{\mathrm{o}}=60^{\circ}\mathrm{F}, p_{\mathrm{O}}=1\mathrm{~atm}\).
the ammonia increases by \ ( 2 5 \ % \ ) , while
