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.
