MCQ
The internal energy of the gas increases $\ln$
  • A
    Adiabatic expansion
  • ✓
    Adiabatic compression
  • C
    lsothermal expansion
  • D
    Isothermal compression
✓

Answer

Correct option: B.
Adiabatic compression
(b) In adiabatic process $\Delta U=-\Delta W$. In compression $\Delta W$ is negative, so $\Delta U$ is positive i.e. internal energy increases.
