A piece of copper metal is initially at 83.0°C. It is dropped into a coffee cup calorimeter containing 30.0 9 of water at a temperature of 10.0°c. After stirring, the final temperature of both copper and water is 25.0°c. Assuming no heat losses, and that the specific heat (capacity) of water is 4.18 J/(g.), what is the heat capacity of the copper in J/K?

A coffee-cup calorimeter has 44.1 g of water at 23.7 °C. A sample of copper weighing 12.7 g is heated in a boiling water bath to have an initial temperature of 100.0°C. The hot copper is then added to the water in the coffee-cup calorimeter. Given that the specific heat of solid copper is 0.385 J/(g·°C), calculate the final temperature of the water (and the copper) in the calorimeter.

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...

A 69.62 g block of lead is heated to 99.48ºC and is placed into a coffee-cup calorimeter filled with 75.67 g of water initially at 22.07ºC. The final temperature was measured as 24.58ºC. The calorimeter heat capacity is 1.860 J/ºC and the specific heat of water is 4.184 J/ g ºC. Based on this information, what is the specific heat of lead? a.0.1473 J/ g ºC b.0.1481 J/ g ºC c.0.1523 J/ g ºC d.0.1533 J/ g ºC e.0.2109 J/...

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. A chunk of copper weighing 18.61 grams and originally at 98.53 °C is dropped into an insulated cup containing 82.09 grams of water at 21.10 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.83...
