The temperature of 170 g of water at 50° C is lowered to 5° C by adding certain amount of ice to it. Find the mass of ice added. Given : specific heat capacity of water = 4200 J kg^-1 K^-1 and specific latent heat of ice = 336000 J kg^-1.

Find the result of mixing 10 g of ice at -10° C with 10 g of water at 10° C. Specific heat capacity of ice = 2.1 J g^-1 K^-1, specific latent heat of ice = 336 J g^-1, and specific heat capacity of water = 4.2 J g^-1 K^-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.

250 g of water at 30° C is contained in a copper vessel of mass 50 g. Calculate the mass of ice required to bring down the temperature of the vessel and it's contents to 5° C. Given specific latent heat of fusion of ice = 336 x 10³ J kg^-1, specific heat capacity of copper = 400 J kg^-1 K^-1, specific heat capacity of water is 4200 J kg^-1 K^-1.
