Change of State

What is the latent heat of fusion and latent heat of vaporisation of $10 \mathrm{g}$ of ice and water, respectively?

Which of these changes can be reversed?

How much heat is required to convert $10 \mathrm{g}$ of ice at $-5°\mathrm{C}$ to water at $10°\mathrm{C}$? (Given specific heat of ice $=0.5 \mathrm{cal} {\mathrm{g}}^{-1}{}^{\circ }\mathrm{C}^{-1}$, specific heat of water $=1.0 \mathrm{cal} {\mathrm{g}}^{-1}{}^{\circ }\mathrm{C}^{-1}$, Latent heat of fusion $=80 \mathrm{cal} {\mathrm{g}}^{-1}$)
