How many grams of steam at 100C are required to melt 200 grams of ice? Heat fusion for ice at 0C is 334J/g. Heat of vaporization of water at 100C is 2,230J/g.
Calculate how many grams of ice at 0°C would be melted by 100 g of 100°C steam. Hint: heat will be transferred from the steam to the ice in two processes: •the steam will condense into liquid, and •that liquid will transfer heat until it is at the freezing point of water. Note that for water: Lf = 80 cal/g (ice), and Lv = 540 cal/g (steam) (Use calories) C(water) =1 cal/g*C Answer in grams no decimal places.

MCQ7 (4 marks) Five statements are given below (i) f heat is supplied to ice at -10°C some ice always melts. (i) The heat evolved by steam at 110-C condensing to water at 100C is (mass) x (latent heat). (iii) If more heat than (mass) x (latent heat) is removed from ice at O'C the final temperature will be <oc (h) lf less heat than (mass) x (latent heat) is removed from ice at 0"C the final temperature will be>...
How many calories are needed to convert 125 grams of water at 75.0 C to steam at 100.0 C? [Specific heats: ice = 0.495, water = 1.00 steam = 0.478 cal/g C] [water's heat of fusion = 80.0 cal/gram, water's heat of vaporization - 540.0 cal/gram] 3125 cal 3330 cal 6875 cal 13,125 cal 70,625 cal
