A well-insulated aluminum calorimeter cup with mass of 205 g contains 255 g of liquid water at 21.7 °C. A 287-g silver figure of polar bear, with initial temperature of 96.5 °C, is dropped into the water. What is the final temperature of the water, cup, and bear when they reach thermal equilibrium? The specific heats of silver, aluminum, and liquid water are, respectively, 234 J/(kg.K), 910 J/(kg:K), and 4190 J/(kg.K). Number 26.2 тос Incorrect. You might have neglected to...

A calorimeter was used to measure the heat change when an ionic compound dissolves in water. The final mass of the contents of the calorimeter was 50.70 g and the change in temperature was 2.00 °C. An insulated coffee cup is filled with a liquid and fully enclosed at the top, except for a small hole for a thermometer. Calculate the heat change of the calorimeter contents, given that its specific heat is 4.13 J/(g⋅°C.) Calculate the heat change of...

a.
In the laboratory a "coffee cup"
calorimeter, or constant pressure calorimeter, is
frequently used to determine the specific heat of a solid, or to
measure the energy of a solution phase reaction.
Since the cup itself can absorb energy, a separate experiment is
needed to determine the heat capacity of the calorimeter. This is
known as calibrating the calorimeter and
the value determined is called the calorimeter
constant.
One way to do this is to use a common metal...
