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 first law of thermodynamics |
\[\Delta U=Q+W\] |
For isothermal process, \[\Delta U=0\] |
\[\therefore \] \[Q=-W\] |
Given, \[W=-150\] |
\[\therefore \] \[Q=+150\] |
When Q is positive, the heat is added to the gas. |
