Answer #1

A cube of ice is taken from the freezer at -6.5 ∘C and placed in
a 95-g aluminum calorimeter filled with 300 g of water at room
temperature of 20.0 ∘C. The final situation is observed to be all
water at 16.0 ∘C. The specific heat of ice is 2100 J/kg⋅C∘, the
specific heat of aluminum is 900 J/kg⋅C∘, the specific heat of
water is is 4186 J/kg⋅C∘, the heat of fusion of water is 333
kJ/Kg.

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)

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...
