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.

Ice at -42 C was warmed to steam at 134 C. How much energy, in calories, was gained to warm 250 g of ice to steam? (get the sign right!) Specific heat H2O(g) = 0.48 cal/gram-C, Specific heat H2O(s) = 0.5 cal/gram-C. Specific heat H2O(l) = 1.0 cal/gram-C. Heat of vaporization H2O = 540 cal/gram, Heat of fusion H2O = 80 cal/gram.
