Question 978: Thermodynamics & KTG

Question

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

Accepted Answer

Internal energy depends only on the initial and final states of temperature and not on the path. In a cyclic process, as initial and final states are the same, change in internal energy is zero. Hence E is $$\Delta $$U, the change in internal energy.

Answer

E = 0

Answer

Q = 0

Answer

W = 0

Answer

Q = W = 0
