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 Sarring rod A student heats 60.57 grams of lead to 98.03 °C and then drops it into a cup containing 75.53 grams of water at 24.16 °C. She measures the final temperature to be 26.41 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.60 J/°C. Water Assuming that no heat is lost to the surroundings calculate the specific heat of lead. Metal sample Specific Heat (Pb) = |J/g°C. Th d 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 Scirring 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 calorimeter constant. One way to do this is to use a common metal of known heat capacity. In the laboratory a student heats 95.18 grams of iron to 98.68 °C and then drops it into a cup containing 81.44 grams of water at 24.08 °C. She measures the final temperature to be 32.28 °C. Water Metal- sample Using the accepted value for the specific heat of iron (See the References tool), calculate the calorimeter constant. 20 Then C Calorimeter Constant = | J/°C.

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 A chunk of lead weighing 18.11 grams and originally at 97.74 °C is dropped into an insulated cup containing 77.77 grams of water at 20.67 °C. Stirring rod The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.82 J/°C. Water Metal Using the accepted value for the specific heat of lead (See the References tool), calculate the final temperature sample of the water.
