Answer #1

Fist the temperature of Ice will raise from -10 to 0 then its state will change from solid to liquid. Further, the temperature of the water will rise from 0 to 100 then it changes its state from liquid to vapor. After that finally, the temperature will rise from 100 to 150. Hence total energy required will be
