The heat of fusion of ice is 80 cal/g. How many calories are required to melt 1.0 mol of ice? 1.4 x 103 cal None of these 0.23 cal 6.9 x 10-4 cal 4.4 cal
how much heat in kilocalories is required to melt 2.9 mol of isopropyl (molar mass=60.0g/mol) the heat fusion and heat vaporization of isopropyl are 21 4 cal/g and 159 cal/g
Heat is added to 0.91 kg of ice at -6 °C. How many kilocalories are required to change the ice to steam at 138 °C? Hint: This involves two phase changes and heating the ice water and steam. Be sure to use the right latent heats and specific heats
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.
Solid ice melts at 0 °C and has a latent heat of fusion of 333 kJ/kg. How much heat is required to first melt 0.02 kg of ice into water at 0 °C, and then increasing the temperature of the water from 0 °C to 16.6 °C?

Heat is added to 2.31 kg of ice at -23 °C. How many kilocalories are required to change the ice to steam at 155 °C?
Heat is added to 1.91 kg of ice at -16 °C. How many kilocalories are required to change the ice to steam at 128 °C?
Heat is added to 2.21 kg of ice at -14 °C. How many kilocalories are required to change the ice to steam at 144 °C?
Help The formation of condensation on a glass of ice water causes the ice to melt faster than it would otherwise. If 7.42 g of condensation forms on a glass containing water and 397 g of ice, how many grams will melt as a result? Assume no other heat transfer occurs. The latent heat of vaporization of water is 539 kcal/kg and the latent heat of fusion for ice is 79.8 kcal/kg.
Suppose you have 260 g of ice at -40°C. As a rough estimate, suppose that the specific heat of ice is 0.5 cal/(g·°C). Also, the latent heat of fusion is 80 cal/g. How much heat must be added in order to convert the ice to 0°C water? cal
