The change in entropy ie, dS=( textheat textabsorbeb textby textsystem/ textabsolute texttempesrature) or dS=(dQ/T) dQ=0 for adiabatic process. Therefore, entropy change is zero for adiabatic process.

Isobaric

Isothermal

Adiabatic

None of these

The change in entropy ie, $d S = \frac{heat absorbeb by system}{absolute tempesrature}$ or $d S = \frac{d Q}{T}$ $d Q = 0$ for adiabatic process. Therefore, entropy change is zero for adiabatic process.
