Question

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 Thermometer Water Metal sample 2003 Thomson Brooks Cole Stirring rod 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 calorimeted cs One way to do this is to use a common metal of known heat capacity In the laboratory a student heats of iron to 99 15 C and then drops it into a cup containing 83 40 grams of water at 22 38 C She measures temperature to be 30 54 C Using the accepted value for the specific heat of iron See the References tool calculate the calonitrieter 1 C
