A cube of ice is taken from the freezer at -8.50 oC and placed
in an 85 g aluminum calorimeter filled with 310 g of water at room
temperature of 20.0°C. The final situation is all water at 17.0°C.
What was the mass of the ice cube in gram? (Lf = 3.3x105 J/kg,
cwater = 4186 J/kg.C, cAl = 900 J/kg.C, and cice = 2100 J/kg.C)

A (18) g ice cube at –15.0°C is placed in (126) g of water at
48.0 degreesC. Find the final temperature of the system when
equilibrium is reached. Ignore the heat capacity of the container
and assume this is in a calorimeter, i.e. the system is thermally
insulated from the surroundings. Give your answer in degreesC with
3 significant figures.
Specific heat of ice: 2.090 J/(g∙ oC)
Specific heat of water: 4.186 J/(g∙ oC)
Latent heat of fusion for water:...

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...

1. You need design a freezer that will keep the temperature
inside a -5.0 C and will operate with a temperature inside at 5.0 C
and will operate in a room with a temperature of 22.0 C. The
freezer is to make 20.0 kg of ice at 0.0 C starting with water at
20.0 C. For water, the specific heat is 4190 J/kg-K, the heat of
fusion is 333 kj/kg.
a. How much energy must be removed from the water...
