Entropy change in reversible adiabatic process is:

Entropy is a measure of randomess of system. When a liquid is converted to the vapour state entropy of the system increases. Entropy in the phase transformation is calculated using Delta S = (Delta H)/(T) but in reversible adiabatic process Delta S will be zero. The rise in temperature in isobaric or isochoric process increases the randomness of system, which is given by Delta S = "2.303 n C log"((T_(2))/(T_(1))) C = C_(P) or C_(V) Entropy change in a reversible adiabatic process is
