Melting point of ice

19 g of water at 30^oC and 5 g of ice at –20^oC are mixed together in a calorimeter. What is the final temperature of the mixture? Given specific heat of ice = 0.5 cal g^–1 (^oC)^–1 and latent heat of fusion of ice = 80 cal g^–1

80 g of water at 30^oC are poured on a large block of ice at 0^oC. The mass of ice that melts is

The saturation vapour pressure of water at 100^oC is

Two spheres made of same substance have diameters in the ration 1:2. Their thermal capacities are in the ratio of

If mass energy equivalence is taken into account, when water is cooled to form ice, the mass of water should

Compared to a burn due to water at 100^oC, a burn due to steam at 100^oC is

Two liquids A and B are at 32^oC and 24^oC. When mixed in equal masses, the temperature of the mixture is found to be 28^oC. Their specific heats are in the ratio of
