Approximately how many ice cubes must melt to cool 1150 milliliters of water from 29°C to 0°C? Assume that each ice cube contains 1 mole of H2O and is initially at 0°C. ∆H(fusion) = 6.02 kJ/mol; ∆H(vaporization) = 40.7 kJ/mol c(solid) = 2.09 J/g°C; c(liquid) = 4.18 J/g°C; c(gas) = 1.97 J/g°C Enter your answer numerically.
If 1340 kJ of heat is required to melt 4.00 kg of ice at 0 ℃℃ into water at 0 ℃℃ , what is the heat of fusion of water?
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.

6. (review) How much heat must be absorbed by 70.0 g of ice at -10.0 C to transform it into 70.0 g of liquid water at 40.0 °C? The heat of fusion of ice is 333 kJ/kg. The specific heat of water is 4190 J/kg K, and the specific heat of ice is 2028 J/kg K
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 ice (in grams) would have to melt to lower the temperature of 351 mL of water from 26 ∘C to 6 ∘C? (You must consider the enthalpy in cooling the water, as well as the enthalpy in melting the ice and the enthalpy to heat the melted ice from 0∘C up to the system's final temperature of 6 ∘C. Also assume that the density of water is 1.0 g/mL.)
