CTHERMOCAIEMISTRY Solving a basic calorimetry problem thermometer -1 A 54.4 g sample of iron, which has a specific heat capacity of 0.449 J'g contains 150.0 g of water. The temperature of the water starts off at 19.0 °C. When the temperature of the water stops changing ', is put into a calorimeter (see sketch at right) that insulated container it's 22.0 °C. The pressure remains constant at 1 atm. water Calculate the initial temperature of the iron sample. Be sure your answer is rounded to the correct number of significant digits. sample a calorimeter
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. Themeter Mod 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 of known heat capacity. In the laboratory a student heats 92.55 grams of zinc to 97.73 °C and then drops it into a cup containing 78.30 grams of water at 21.37 °C. She measures the final temperature to be 28.88 °C. Using the accepted value for the specific heat of zinc (See the References tool), calculate the calorimeter constant.
