100g of water at 25°C is poured into an insulating cup. 50g of ice at 0°C is added to the water. The water is stirred until the temperature of the water has fallen to 0°C. 18g of ice remains unmelted. The specific heat capacity of water is 4.2J/g°C. Which value does this experiment give for the specific latent heat of fusion of ice?

Dry steam is passed into a well lagged copper can of mass 250g containing 400g of water and 50g of ice at 0degreeC. The mixture is well stirred and the steam supplied is cut off when the temp of the can and its content reaches 20degreeC.Neglecting heat losses, find the mass of steam condensed.
[Specific heat capacity of water=4.2jg-1k-1, specific heat capacity of copper=0.4jg-1k-1, specific latent heat of steam=2260j/g, specific latent heat of ice=336j/g]?
