A piece of ice of mass 40 g is added to 200 g of water at 50° C. Calculate the final temperature of water when all the ice has melted. Specific heat capacity of water = 4200 J kg^-1 K^-1 and specific latent heat of fusion of ice = 336 x 10³ J kg^-1.

Calculate the mass of ice needed to cool 150 g of water contained in a calorimeter of mass 50 g at 32°C such that the final temperature is 5°C. Specific heat capacity of calorimeter = 0.4 J g^-1 °C^-1, Specific heat capacity of water = 4.2 J g^-1 °C^-1, Latent heat capacity of ice = 330 J g^-1.

2 kg of ice melts when water at 100° C is poured in a hole drilled in a block of ice. What mass of water was used? Given: Specific heat capacity of water = 4200 J kg^-1 K^-1, specific latent heat of ice = 336 × 10³ J Kg^-1.

Calculate the total amount of heat energy required to convert 100 g of ice at -10° C completely into water at 100° C. Specific heat capacity of ice = 2.1 J g^-1 K^-1, specific heat capacity of water = 4.2 J g^-1 K^-1, specific latent heat of ice = 336 J g^-1.
