Volume: $\Delta S = nR\ln \frac{V_{2}}{V_{1}}$
Temperature: $\Delta S = nC\ln \frac{T_{2}}{T_{1}}$

Re: entropy

entropy is the measure of disorder or random activity in a system, whereas enthalpy is a measure of the overall energy is a system

Re: entropy

Enthalpy ('H') refers to the measure of total heat content in a thermodynamic system under constant pressure whereas enthalpy is calculated in terms of change. Keep in mind the the SI unit of enthalpy is joules (J).

Re: entropy

Entropy (S) is the measure of disorder. Enthalpy (H) is the measure of total heat content.

Re: entropy

Enthalpy is the delta H and Entropy is the delta S. Basically Enthalpy is the total energy in the system and entropy is the measure of disorder. Also, note that the second law of thermodynamics shows that disorder is increasing.
