The thermodynamic property that measures...

The thermodynamic property that measures the extent of molecular disorder is called entropy. Entropy change of phase transformation can be calculated using Trouton's formula `(DeltaS = DeltaH//T)`. In the reversible adiabatic process, however, `DeltaS` will be zero. the rise in temperature in isobaric and isochoric conditions is found to increase the randomness or entropy of the system.
`DeltaS = 2.303 C log (T_(1)//T_(2))`
The melting point of a solid is `200K` and its latent heat of fusion is `400cal mol^(-1)`. The entropy changes for the fusion of `1` mole of the solid (in cal `K^(-1))` at the same temperature would be

DeltaS = 2.303 C log (T_(1)//T_(2)) When 1 mol of an ideal gas is compressed to half of its volume, its temperature becomes half. Then the change in entropy (DeltaS) would be

The entropy change for a phase transformation 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
