What is meant by absolute entropy?

In which of the following processes is $\Delta S$ positive?

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.

$18 \ g$ of ice is converted into water at $0 \ ^\circ C$ and $1 \ atm$. The entropies of $H_2O_{(s)}$ and $H_2O_{(l)}$ are $38.2$ and $60 \ J/mol \ K$ respectively. The enthalpy change for this conversion is ..... $J/mol$.

The enthalpy of vaporisation of a certain liquid at its boiling point of $35^{\circ} C$ is $24.64 \ kJ \ mol^{-1}$. The value of change in entropy for the process is

$9.0 \, g$ of $H_2O$ is vaporized at $100 \, ^\circ C$ and $1 \, atm$ pressure. If the latent heat of vaporization of water is $x \, J / g$,then $\Delta S$ is given by :-
