You order a 16 oz glass of tea (where the mass of water is 474 grams) from a local restaurant. The tea is freshly brewed and has an initial temperature of 28.93 °C. You add ice to cool it. If the heat of fusion of ice is 6.020 kJ/mol and each ice cube contains exactly 1 mol of water (assume the ice does not add anymore volume), how many ice cubes are necessary to cool the tea to 1.54 °C? The specific heat of the "tea" is 4.184 J/g°C.

    10) How many grams of ice do I need to add to the 356 grams of my soda if I wish to lower the temperature of my soda from 21.8°C to 3.9°C. Assume that the specific heat of the soda is 4.172 J/g⋅C°. The specific heat of water is 4.184 J/g⋅C°. The heat capacity of the glass is 56.4 J/C°. The molar enthalpy of fusion (melting) of ice is 6.018 kJ/mol.

    Calculate the heat required in Joules to convert 18.0 grams of water ice at a temperature of -20° C to liquid water at the normal boiling point of water. Given: -specific heat of ice = 2.09 J/g°C -specific heat of liquid water = 4.184 J/g°C -specific heat of water vapor = 2.03 J/g°C -molar heat of fusion of water = 6.02 kJ/mol -molar heat of vaporization of water = 40.7 kJ/mol
