g of water at

50^{o}

C is lowered to

5^{o}

C by adding certain amount of ice to it. Find the mass of ice added. Given: Specific heat capacity of water

= 4200

k g^{- 1}

^{0} C^{- 1}

k g^{- 1}

A piece of ice of mass 40g is added to 200g of water at 50 degree Celsius. Calculate the final temperature of water when all the ice has melted. Specific heat capacity of water =4200 J per kg per K and specific latent heat of fusion of ice=336*1000 J per kg.

Q 8)

250 g of water at 30 degree celsius is contained in a copper vessel of mass 50g.Calculate the mass of ice required to bring down the temperature of the vessel and its contents to 5 degeree celsius.Specific latent heat of fusion of ice 336*1000 J per kg.

Specific heat capacity of copper =400 J per kg per K Specific heat Capacity of water =4200J per kg per K.

By adding some amount of ice, the temperature of 500g of water at $50^{\circ} C$ , is lowered to $0^{\circ} C$ . If the specific heat capacity of water is 4.2 J g⁻¹ K⁻¹and specific specific latent heat of ice is 336 J g⁻¹, then find the mass of ice added to it.
