Question

Which one of the following equations does not correctly represent the first law of thermodynamics for the given processes involving an ideal gas? (Assume non –
expansion work is zero)
(A) Adiabatic process: ∆U = –w (B) Isochoric process: ∆U = q
(C) Cyclic process: q = –w (D) Isothermal process: q= –w

Answer 1

Answer:

D. will be incorrect answer

in isothermal process heat is zero and

U = w
