A) 300 J of heat has been added to the gas
B) no heat is transferred because the process is isothermal
C) 150 J of heat has been added to the gas
D) 150 J of heat has been removed from the gas
Correct Answer: C
Solution :
From the first law of thermodynamics \[\Delta U=Q-W\] For isothermal process, \[\Delta U=0\] \[\therefore \] \[Q=-W\] Given, \[W=-150\,J.\] \[\therefore \] \[Q=+150\,J\] When Q is positive, the heat is added to the gas.You need to login to perform this action.
