An ice bag containing 0°C ice is much more effective in absorbing heat than one containing the same amount of 0°C water. The specific heat capacity of water is 1.00 kcal/(kg - °C), and its latent heat of fusion is 79.8 kcal/kg. (a) How much heat in kcal is required to raise the temperature of 0.930 kg of water from 0°C to 30.0°C? kcal (b) How much heat is required to first melt 0.930 kg of 0°C ice and then...

You pour 210 g hot coffee at 78.7 degree C and some cold cream at 7.50 degree C to a 115-g cup that is initially at a temperature of 22.0 degree C. The cup, coffee, and cream reach an equilibrium temperature of 63.0 degree C. The material of the cup has a specific heat of 0.2604 kcal/(kg middot degree C) and the specific heat of both the coffee and cream is 1.00 kcal/(kg middot C). If no heat is lost...
