1. The problem statement, all variables and given/known data Calculate the amount of heat to be added to warm 150g of ice from -10C to produce steam at 110C. 2. Relevant equations Ice = cice = 0.5cal/gC, L = 80 cal/g. Water = Cw = 1.0 cal/gC; Steam = csteam = 0.5 cal/gC; Lv = 540 cal/g 3. The attempt at a solution I know the answer should be 109.5kcal. I have found 12,000 cal. BUT I HAVE ABSOLUTELY NO IDEA HOW TO GET TO 109kcal. I JUST NEED SOME DIRECTION.
