A cabe of iron (density = 8000kg m^(-1) specific beat capacity = 470g J kg^(-1)K^(-1)) is heated to a high temperature and is placed on a larger block of ice at 0^(@)C The cubemelts the ice below it displaces the water and sinks in the final equilibriumposition its upper surface just inside the ice calculate th initial temperature of the cube .Noglect any loss of head outside the ice and the cube .The density of ice = 900 kg m^(-1) and the latent head of fasion of ice = 3.36 xx 10^(5)J kg^(-1)

Calculate the amount of ice, which is sufficient to cool 45g of water, contained at 30^(@)C , such that the final temperature of the mixture is 10^(@)C . (Take specific latent heat of fusion of ice is 336" J "g^(-1) )

33.6 cc of phosphorous vapour weighs 0.0625 g at 546^(@)C and 76 cmHg pressure. What is the molecular weight of phosphorous? How many atoms are there in one molecule of phosphorous vapour?
