10 gm of ice at 0°C is kept in a calorimeter of water equivalent 10 gm. How much heat should be supplied to the apparatus to evaporate the water thus formed? (Neglect loss of heat)

How much heat should be supplied to convert ice of mass 50 g at 0^@C into water at 40^@ C ?

How much heat is required to melt 5 gm ice?

How much heat should be supplied to convert ice of mass 250 g at 0^(@)C into water at 20^(@)C ?

30 gm of ice at 0^@C is placed in a calorimeter of mass 20 gm also at 0^@C . 100 gm of water at 90^@C is poured into the calorimeter. Find the final temperature. (specific heat of calorimeter = 0.4 cal//gm ^@C , Specific heat of water = 0.42 cal//gm ^@C Latent heat of fusion of ice = 80calg )

10 gm of ice at -20^(@)C is dropped into a calorimeter containing 10 gm of water at 10^(@)C , the specific heat of water is twice that of ice. When equilibrium is reached the calorimeter will contain:
