What is the entropy change in $J K^{-1}$ during the melting of $27.3 \ g$ of ice at $0^{\circ} C$? (Latent heat of fusion of ice $= 330 \ J g^{-1}$)

For which one of the following reactions is the entropy change positive?

When naphthalene is heated strongly,it undergoes sublimation. What happens to the entropy of the system?

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

Why does the entropy of a substance increase with an increase in temperature?

If the enthalpy of vaporization for water is $186.5 \ kJ \ mol^{-1}$,the entropy of its vaporization will be ...... $J \ K^{-1} \ mol^{-1}$ (Assume the boiling point of water is $373 \ K$).
