Which of the following processes exhibits increase in internal energy?

Options

  1. AAdiabatic compression of gas.
  2. BAdiabatic expansion of gas.
  3. CIsothermal expansion of gas.
  4. DIsothermal compression of gas.

Correct answer

A. Adiabatic compression of gas.

Step-by-step solution

In adiabatic process, there is no exchange of heat between system and its surroundings. So, - U =- W or U = W During compression work is done on the system by the surroundings. Therefore, W is positive. Thus, the internal energy would increase during the adiabatic compression of a gas.
