Three moles of an ideal monoatomic gas performs a cycle 1 ® 2 ® 3 ® 4 ® 1 as shown. The gas temperature in different states are, T1 = 400 K, T2 = 800 K, T3 = 2400 K and T4 = 1200 K. The work done by the gas during the cycle is –
A
1200 R
B
3600 R
C
2400 R
D
2000 R
Answer
2400 R
Explanation
Solution
W1®2 = 0
W2 ® 3 = nR (T3 – T2)
W3 ® 4 = 0
W4 ® 1 = nR (T1 – T4)
