A spontanous change is always accompanied by an increase in entropy'. The entropy change referred to in this statement is

Many spontaneous processes are accompanied by decrease in entropy-explain.

Give the units of entropy and entropy change.

The entropy change for a phase transformation is :

The entropy change for a phase transformation is :

The entropy change in adiabatic process is

The entropy change for a phase transformation is :

The process of evaporation of a liquid is accompanied by: increase in enthalpy decrease in entropy no change in free energy increase in entropy.
