Effects of Heat: Change in Physical State

An ice cube is heated and the variation of its temperature with time is shown. The process representing the conversion of water into steam is 

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 $=80 \mathrm{cal} {\mathrm{g}}^{-1}$)

$50 \mathrm{g}$ of steam at $100° \mathrm{C}$ is passed into a large block of ice at $0° \mathrm{C}$ the mass of ice that melts is 

Water and ice having equal masses are placed inside an insulated container. The initial temperatures of water and ice are $40°\mathrm{C}$ and $0°\mathrm{C}$ respectively. The equilibrium temperature of the system in degrees Celsius is close to (Note: take the specific heat of water $=4000 \mathrm{J}·{\mathrm{kg}}^{-1}·{\mathrm{K}}^{-1}$; latent heat of fusion $=300 \mathrm{kJ}·{\mathrm{kg}}^{-1}$ )
