A piece of copper of mass 400g at a temperature of 1000°c us quickly transfered to a vessel of negligible thermal capacity containing 300g of water at 26°c.If the final steady temperature of the mixture is 108°c. Calculate the mass of the water boiled away. {specific beat capacity of copper Cc= 400Jkg-1k-1.
specific heat capacity of water Cw= 4200Jk-1.
Specific latent heat of vaporisation of steam = 2260000Jkg-1}.?
