When 25 g of ice at -20°c have absorbed 2500 cal of heat, what os the temperature of the resulting water?
Heat required by ice to melt to water
Heat given is 2500 cal
Heat given is more than required thus all ice melt and then temperature rises.
Heat responsible to rise the temperature of water=2500-200=500cal
TF=500/25=20 degree Centigrade
