A well-insulated 0.2kg copper bowl contains 0.10kg of ice, both at −10◦ C. A very hot 0.35kg copper cylinder is dropped into it and the lid quickly closed. The final temperature of the system is 100◦C, with 5g of steam in the container.
(a) How much heat was transferred to the water (in all phases);
(b) How much to the bowl?
(c) What must have been the original temperature of the cylinder?
The specific heat of copper is 386 J/kg·K.
The specific heat of ice is 2100 J/kg·K
The latent heat of fusion of ice is 333 kJ/kg.
The specific heat of liquid water is 4186J/kg·K.
The latent heat of vaporization of water is 2260kJ/kg
