MCQ
A given system undergoes a change in which the work done by the system equals the decrease in its internal energy. The system must have undergone an
- Alsothermal change
- ✓Adiabatic change
- Clsobaric change
- DIsochoric change
✓
Answer
Correct option: B.
Adiabatic change
In adiabatic change $Q=$ constant $\Rightarrow \Delta Q=0$
So $(\Delta W=\Delta U(\because \Delta Q=\Delta U+\Delta W)$
So $(\Delta W=\Delta U(\because \Delta Q=\Delta U+\Delta W)$
