A) 13.2 J
B) 15.4 J
C) 12.6 J
D) 16.8 J
Correct Answer: B
Solution :
[b] In the first-case adiabatic change, \[\Delta Q=0,\Delta W=-35J\] From 1st law of thermodynamics, \[\Delta Q=\Delta U+\Delta W,\] In the second case \[\Delta Q=12cal=12\times 4.2\text{ }J=50.4\text{ }J\] \[\Delta W=\Delta Q-\Delta U=50.4-35=15.4J\]You need to login to perform this action.
