How should `2kg` of water at `60^(@)C` be divided so that when one part of it is turned into ice at `0^(@)C` it would give out sufficient heat to vaporize the other part? (Specific latent heat of fusionof ice `=336xx10^(3)J kg^(-1)` and specific latent heat of vaporization of steam `=2250xx10^(3)Jkg^(-1)`)
