When naphthalene is heated strongly,it undergoes sublimation. What happens to the entropy of the system?

The enthalpy change for the conversion of water into vapor at $27^\circ C$ is $30 \ kJ/mol$. The entropy change for this process in $J/mol \ K$ is:

Mixing of non-reacting gases is generally accompanied by

Let us consider a reversible reaction at temperature,$T$. In this reaction,both $\Delta H$ and $\Delta S$ were observed to have positive values. If the equilibrium temperature is $T_e$,then the reaction becomes spontaneous at:

The enthalpy of vaporization of water is $186.5 \, kJ \, mol^{-1}$. What is the entropy of vaporization in $kJ \, K^{-1} \, mol^{-1}$?

Which of the following reactions has a positive entropy change?
