For an adiabatic process, which one of the following is wrong statement? (a) Equation of state is pVγ = constant (b) There is exchange of heat with surrounding (c) All the work is utilised to change the internal energy of the system (d) Temperature of the system changes i.e. Δ T ≠ 0

Answer: (b). Adiabatic: no heat exchange with the surroundings, so (b) is wrong. pVγ = constant (a), W = -Δ U (c) and Δ T ≠ 0 (d) are all correct. So the wrong statement is (b).

For an adiabatic process, which one of the following is wrong statement?

Show answer and solution

Answer: (b)

Adiabatic: no heat exchange with the surroundings, so (b) is wrong.
$pV^{\gamma}$ = constant (a), $W = -\Delta U$ (c) and $\Delta T \neq 0$ (d) are all correct.
So the wrong statement is (b).
