Question

Does entropy change in the adiabatic process?

Answer 1

Adiabatic processes are characterized by an increase in entropy, or degree of disorder if they are irreversible and by no change in entropy if they are reversible.

$$\begin{gathered} \mathrm{In}\mathrm{adiabatic}\mathrm{process},\mathrm{q}=0 \\ ∆\mathrm{S}=\frac{\mathrm{q}}{\mathrm{T}} \\ ∆\mathrm{S}=0 \end{gathered}$$
