A) the temperature of the system will be increase 50 J
B) the temperature of the system will be constant
C) the internal energy of the system will be increase 50 J
D) the internal energy of the system will be decrease 50 J
Correct Answer: D
Solution :
From first law of thermodynamics \[dQ=dU+dW\] For adiabatic process\[dQ=0\] \[\therefore \] \[dU+dW=0\] \[dU=-50\,J\] Therefore, the internal energy of system will decrease.
