1.a In the laboratory a student uses a "coffee cup" calorimeter to determine the specific heat of a metal. She heats 18.7 grams of chromium to 98.51°C and then drops it into a cup containing 84.8 grams of water at 24.15°C. She measures the final temperature to be 25.94°C. Assuming that all of the heat is transferred to the water, she calculates the specific heat of chromium to be J/g°C. 1.b An electric range burner weighing 660.0 grams is turned...

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 student heats 64.65 grams of tungsten to 99.08 °C and then drops it into a cup containing 82.26grams of water at 24.43 °C. She measures the final temperature to be 26.31 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined...

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 student heats 66.90 grams of silver to 98.61 °C and then drops it into a cup containing 81.04 grams of water at 24.12 °C. She measures the final temperature to be 27.32 °C. The heat capacity of the calorimeter was determined in a separate experiment to be 1.87 J/°C. Assuming that no heat is lost to the surroundings calculate the specific heat of silver.
