Question

deduce the mathematical expression of first law of thermodynamics for the following 1) Isothermal process​

Answer 1

Answer:

isothermal means temperature is constant there is no change in temperature

and internal energy is function of temperature

∆U = Cv∆T when no change jn temprature ∆T=0

so ∆U =0

so first law q= ∆U + W

becomes q = W
