PART A: A student constructs a coffee cup calorimeter and places 50.0 mL of water into it. After a brief period of stabilization, the temperature of the water in calorimeter is determined to be 19.6 °C. To this is added 50.0 mL of water that was originally a temperature of 54.5 °C. A careful plot of the recorded temperature established T0 as 31.1 °C. What is the calorimeter constant (J/°C)? DensityH2O = 1.00 g/mL Specific HeatH2O = 4.184 J/g·°C PART...

In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat capacity of a solid, or to measure the enthalpy change of a solution phase reaction. A student heats 63.86 g silver to 98.97 °C and carefully lowers it into a cup containing 84.07 g water at 20.70 °C. She measures the final temperature to be 23.82 °C The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was...

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...
