If Q , E and W denote respectively the heat added, change in internal energy and the work done in a closed cycle process, then

Options

  1. AQ =0
  2. BW=0
  3. CQ = W =0
  4. DE =0

Correct answer

D. E =0

Step-by-step solution

From the 1^ st law of thermodynamics, Q = E + W For cyclic process, E=0, Q=W 0
