In which case is the change in entropy negative?

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

What happens to the entropy of water when it freezes to form an ice cube?

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

For the following process $H_2O_{(l)} (1 \ bar, 373.15 \ K) \rightleftharpoons H_2O_{(g)} (1 \ bar, 373.15 \ K)$, identify the correct set of thermodynamic parameters.

The positive value of $\Delta S$ indicates that
