The internal energy of a gas will increase when it

Options

  1. Aexpands adiabatically.
  2. Bis compressed adiabatically.
  3. Cexpands isothermally.
  4. Dis compressed isothermally.

Correct answer

B. is compressed adiabatically.

Step-by-step solution

In an adiabatic process, U=- W . In compression W is negative, hence U is positive which implies increase in internal energy.
