Question

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 fusion is
333 kJ/kg.

Answer #1

(a) Two 64 g ice cubes are dropped into 278 g of water in a
thermally insulated container. If the water is initially at 25°C,
and the ice comes directly from a freezer at −15°C, what is the
final temperature at thermal equilibrium? (in celcius)
(b) What is the final temperature if only one ice cube is used?
(in celcius)
