Chapter 18, Problem 041
(a) Two 58 g ice cubes are dropped into 410 g
of water in a thermally insulated container. If the water is
initially at 20°C, and the ice comes directly from a freezer at
-11°C, what is the final temperature at thermal equilibrium?
(b) What is the final temperature if only one ice
cube is used? The specific heat of water is 4186 J/kg·K. The
specific heat of ice is 2220 J/kg·K. The latent heat of...

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....
