Question

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 :
  1. Isothermal change
  2. Adiabatic change
  3. Isobaric change
  4. Isochoric change

A
Isothermal change
B
Adiabatic change
C
Isobaric change
D
Isochoric change
Solution
Verified by Toppr

Given dW=dU

So, dW+dU=0

So, dQ=0

The process is adiabatic.
