The molar heat of vaporisation of a liquid is $6 \ kJ \ mol^{-1}$. If the entropy change is $16 \ J \ mol^{-1} \ K^{-1}$,the boiling point of the liquid is:

What is the unit of $\Delta S_m^\circ$?

Fill in the blanks:
$(i)$ The entropy of one mole of a substance at a fixed temperature and standard state is called ........ .
$(ii)$ The unit of molar entropy is .......... .
$(iii)$ The process of conversion of graphite into diamond is of ........ type.

$1$ mole of a diatomic gas is heated through an isochoric process from $300\,K$ to $500\,K$. The change in entropy is: (in $,J/K$)

Identify the reaction/process in which the entropy decreases.

The enthalpy of vaporisation of a liquid is $30 \ kJ \ mol^{-1}$ and entropy of vaporisation is $75 \ J \ K^{-1} \ mol^{-1}$. Calculate the boiling point of the liquid at $1 \ atm$. (in $K$)
