An ideal gas is subjected to cyclic process involving four thermodynamic states, the amount of heat (Q) and work involved in each of these states are:
Q1 = 7000 J, Q2 = -6000 J, Q3 = -4000 J, Q4 = 5000 J
W1 = 2700 J, W2 = -1200 J, W3 = -1800 J, W4 = x J
The value of x is:
1
2300 J
2
2500 J
3
3000 J
4
3500 J
