The change in entropy ie, dS=(heat absorbed by system/absolute tempertaure) or dS=(dQ/T) dQ=0 for adiabatic process. Therefore, entropy change is zero for adiabatic process.

The change in entropy ie, $d S = \frac{h e a t ab sor b e d b y sys t e m}{ab so l u t e t e m p er t a u re}$ or $d S = \frac{d Q}{T}$ $d Q = 0$ for adiabatic process. Therefore, entropy change is zero for adiabatic process.
