Question

Based on the first law of thermodynamics, which one of the following is correct?

A. For an isothermal process, q=+w

B. For an isochoric process, ΔU=-q

C. For an adiabatic process, ΔU=-w

D. For a cyclic reaction, q=-w​

Answer 2

Answer:

Based on the first law of thermodynamics,

∆U=q+W

In a cyclic process,

The initial and final state is same,so in a cyclic process the net change of internal energy is equal to Zero...

∆U=0

So,∆U=q+W

q=-W
