One mole of which of the following has the highest entropy?

Which of the following processes is associated with a decrease in entropy?

For a process to occur spontaneously,

For which of the following processes is the entropy change $(\Delta S)$ negative?
$I)$ Sublimation of dry ice
$II)$ Freezing of water
$III)$ Crystallisation of the dissolved substance
$IV)$ Burning of rocket fuel

One mole of ice is converted into water at $1 \ atm$ and $273 \ K$. The entropies of $H_2O_{(s)}$ and $H_2O_{(\ell)}$ are $38.2$ and $60.01 \ J \ mol^{-1} \ K^{-1}$ respectively. The enthalpy change for the conversion is ...... $J \ mol^{-1}$.

Ice at $-5^{\circ} C$ is heated to become vapor with a temperature of $110^{\circ} C$ at atmospheric pressure. The entropy change associated with this process can be obtained from:
