You have a block of ice at a temperature of -100°C. This block of ice is made from 180g H2O. The block of ice will be heated continually until it becomes super-heated steam at a temperature of 200°C Cice = 2.03 J/g-K ΔHfus=6.01 kJ/mol Cwater = 4.18 J/g-K Csteam = 1.84 J/g-K ΔHvap=40.67 kJ/mol What is the enthalpy change raising the temperature of 180 g of ice at −100 °C to 0°C? What is the enthalpy change upon melting 180...
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.)
How much ice (in grams) would have to melt to lower the temperature of 355mL of water from 25?C to 5?C? (Assume the density of water is 1.0 g/mL.)
How much ice (in grams) would have to melt to lower the temperature of 354 mL of water from 25 ∘C to 6 ∘C? (Assume the density of water is 1.0 g/mL.)
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
