Which of the following is the least $random$ state of water?

The enthalpy of vaporization of benzene is $30.779 \ kJ/mol$ and its boiling point is $353 \ K$. Find the change in entropy for the conversion of liquid benzene to its vapour at that temperature.

If $900 \ J/g$ of heat is exchanged at the boiling point of water,what is the increase in entropy in $J \ K^{-1} \ mol^{-1}$?

Calculate $\Delta S_{\text{total}}$ for a certain reaction if $\Delta H = -150 \ kJ$ and $\Delta S = 32 \ JK^{-1}$ at $300 \ K$. (in $JK^{-1}$)

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 $K$)

Two moles of an ideal gas undergo free expansion from $10 \ L$ to $100 \ L$ at $300 \ K$. The values of $\Delta S_{system}$ and $\Delta S_{surroundings}$ are ($R$ is universal gas constant)
