A stationary mass of gas is compressed without friction from an initial state of 0.3 m 3 and 0.105 M Pa to a final state of 0.15 m 3 and 0.105 M Pa. The pressure remaining constant. During the process there is transfer of 37.6 kJ of heat from the system. During the process the amount of internal energy change is-
Text Solution
Verified by ExpertsThe correct answer is:
B
Δ W = – 105 × (0.15 – 0.3) kJ = + 15.75 kJ
Δ q = – 37 .6 kJ
∴Δ E = Δ W + Δ q = – 37.6 + 15.75 = – 21.85 kJ
