1.	Which of the followingis a formulation offirst law of thermodynamicsa) P ext = P-∆Pb) dw=-P ∆Vc) ∆U=Q+Wd) H=U+P V
Answer» ANSWER: The actual formula of first law of THERMODYNAMICS is ∆U=Q-W where, ∆U=change in internal energy Q=heat ADDED and W=work done by the system.

Answer»

The actual formula of first law of THERMODYNAMICS is

∆U=Q-W

where, ∆U=change in internal energy

Q=heat ADDED and

W=work done by the system.
