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
- A isothermal change
- B adiabatic change
- C isobaric change
- D isochoric change
Answer & Solution
Correct Answer
(B) adiabatic change
Step-by-step Solution
Detailed explanation
As work done, \(\Delta W=\Delta Q-\Delta U\) Since in adiabatic process \(\Delta Q=0\) i.e., there is no exchange of heat, the work done by the system is equal to the decrease in its internal energy.
