(a) How much heat should be provided to ice of 720 g mass, lying at -`10^@C` to melt it to water at `0^@C` ? (b) How much heat should be provided to water at `0^@C` to increase its temperature to `100^@C` ?(c) How much heat should be given to water at `100^@C` to transform it completely into water ?
(d) Totally, how much heat should be given to ice of 720 g at `-10^@C` to convert it completely into vapour ? (C"ice"=2220 "J kg"^(-1) K^(-1), C"water"=4190 "J kg"^(-1) K^(-1) , LF=333 "kJ"/"kg", LV=2256 "kJ"/"kg"`)
