MCQ

A given system undergoes a change in which work done by the system equals the decrease in its internal energy. The system must have undergone:

A
Isothermal change.
B
Adiabatic change.
C
Isobaric change.
D
Isochoric change.

✓

Answer

Adiabatic change.

Explanation:

When a gas expands suddenly, (adiabatic change) work is done by the gas. Therefore, internal energy of the system decreases.
