Question

Answer For A, B, and, C

A closed piston-cylinder system consists of 3.0 moles of
monatomic gas, initially at temperature 120K and pressure 0.75 atm (call this initial state A). It
undergoes the following reversible cyclic process:
A – B: Isothermal compression to one-third its initial volume
B – C: Adiabatic expansion back to its original pressure.
C - A: Isobaric (constant-pressure) expansion back to state A
a.
Determine the initial volume of the gas (point A).
b.
Determine the pressure of the gas at point B.
What is the change in the internal energy of the gas between A and B?
C.
d.
What is the temperature at point B?
What is the heat transfer in process B → C?
e.
f.
What is the volume at point C?
What is the temperature at point C?
h.
What is the heat transfer in process C – A?
i.
How much work was done on the gas in process C → A?
j.
What is the net internal energy change over the entire cycle?
k.
Draw a PV diagram for the cycle. Is this a heat engine or a heat pump?
