One mole of ideal monoatomic gas is carried through the reversible cyclic process as shown in figure. Calculate net heat absorbed by the gas in the path BC.
A
PºVº
B
PºVº
C
2 PºVº
D
PºVº
Text Solution
Verified by ExpertsThe correct answer is:
A
Δ E = q + w
W BC = 
(2Vº – Vº) (Pº – 3Pº) + (2Vº – Vº) (0 – Pº) = – 2PºVº
Δ E = nC V Δ T = 1 × 
R 
= – 
PºVº
q BC = Δ E – W = – 
PºVº + 2PºVº = 
PºVº
