Look up the specific heats of ice, water and steam. Call them Ci, Cw and Cs.
Cw is 1.00 cal/g C
You will also need the heat of fusion
Hf = 80 cal/g
and the heat of vaporization
Hv = 540 cal/g
Q required = 5g * [15Ci + 100Cw + 50 Cs + Hf + Hv] calories
Cw is 1.00 cal/g C
You will also need the heat of fusion
Hf = 80 cal/g
and the heat of vaporization
Hv = 540 cal/g
