Block
What is the final temperature if 300 grams of ice at 0 Co, 500 grams of water at 0 Co and 1200 grams of water at 100 Co are
mixed? (Answer 48 Co)
2.
A calorimeter, specific heat .1 cal/g Co, mass 200 grams, contains 300 grams of water at 40 Co. If 50 grams of ice at 0 Co is
dropped into the water and stirred, the temperature of the mixture when all the ice has melted is 23.8 Co. Determine the heat
of fusion of ice. (Answer 79.88 cal/g Co)
3.
A block of silver, mass 500 grams, temperature 100 Co, is put in a calorimeter with 300 grams of water, temperature 30 Co.
The mass of the calorimeter is 50 grams, and its specific heat is .1 cal/g Co. A 50-gram mass of ice at -10 Co is also put in the
calorimeter. Calculate the final temperature. Assume the final temperature is below 30 Co.
(Answer 20.1 Co)
4.
What is the final temperature attained when 900 grams of ice at 0 Co is dropped into 3400 grams of water at 93.3 Co in a
calorimeter having a mass of 1350 grams with specific heat .09 cal/g Co?
(Answer 58.03 Co)
5.
In an experiment to determine the heat of vaporization of water, 15 grams of steam at 100 Co is added to 150 grams of water
at 20 Co in a calorimeter. The mass of the calorimeter is 75 grams; its specific heat is .1 cal/g Co. The equilibrium
temperature of the mixture is 73.9 Co. Determine the heat of vaporization of water.
(Answer 539.85 cal/g)
6.
A mixture of ice and water, mass 200 grams, is in a 100-gram calorimeter, specific heat .2 cal/g Co. When 40 grams of steam
is added to the mixture the temperature is raised to 60 Co. How many grams of ice were originally in the calorimeter?
(Answer 125 grams)
7.
An aluminum cylinder, mass 50 grams, is placed in a 100-gram brass calorimeter with 250 grams of water at 20 Co. What
equilibrium temperature is reached after the addition of 25 grams of steam at 120 Co?
(Answer 73.35 Co)
