In an experiment, 22.5 g of metal was heated to 98.0°C and then
quickly transferred to 150.0 g of water in a calorimeter. The
initial temperature of the water was 27.0°C, and the final
temperature after the addition of the metal was 32.5°C. Assume the
calorimeter behaves ideally and does not absorb or release
heat.
What is the value of the specific heat capacity (in J/g•°C) of
the metal?

In an experiment, 25.5 g of metal was heated to 98.0°C and then
quickly transferred to 150.0 g of water in a calorimeter. The
initial temperature of the water was 21.0°C, and the final
temperature after the addition of the metal was 32.5°C. Assume the
calorimeter behaves ideally and does not absorb or release
heat.

Answer the following questions:
a) A calorimeter, specific heat capacity 500.0 J/kgC, mass 200.0
g, contains 300.0 g of water at 40.0 C. If 50.0 g of ice at 0.00 C
is dropped into the water and stirred, the temperature of the
mixture when the ice has melted is 23.8 C. Calculate the heat of
fusion of ice.
b) What is the final temperature attained when 900.0 g of ice at
0.00 C is dropped into 3400.0 g of water...

An iron calorimeter of mass 153 g contains 260 g of water. The
system is in thermal equilibrium at +10°C. We place two blocks of
metal in the water: one is a 45 g piece of copper with an initial
temperature of +61°C; the second piece has a mass of 75 g and is
initially at +100°C. The combined system reaches a final
equilibrium temperature of +41°C. Calculate the specific heat
capacity of the unknown second piece of metal.

There is 300 grams of water in the 200-gram calorimeter cup
(inner can). Both are at room temperature of 20 degrees Celsius. A
100-gram metal sample with an initial temperature of 90 degrees
Celsius is placed in the calorimeter resulting. The resulting final
temperature of the system is 30 degrees Celsius. If the calorimeter
can has a specific heat of 0.2 cal/g-C degree, determine the
specific heat of the metal sample
