What is the condition under which heat absorbed at constant volume (∆U = qV) is equal to the change in internal energy?

Options

  1. AWhen pressure is constant
  2. BWhen temperature is constant
  3. CWhen volume is constant
  4. DWhen no work is done

Correct answer

C. When volume is constant

Step-by-step solution

Heat absorbed at constant volume (∆U = qV) occurs when volume is constant, and no work is done.
