imetry

1. imetry Calo r A. __________ is the science associated with determining the changes in energy of a system by measuring the heat exchanged with the surroundings. Calorimetry

2. imetry Calo r 1. A __________ is a device used to measure the quantity of heat transferred to or from an object. calorimeter

3. imetry Calo r A. The calorimeter used in high school science labs is more commonly referred to as a ________ cup. It is a __________ calorimeter-usually filled with water. Styrofoam coffee cup

4. imetry Calo r B. The assumption behind the science of calorimetry is that the energy gained or lost by the water is _____ to the energy lost or gained by the object under study. equal

5. imetry Calo r 1. And in fact, the quantity of energy gained or last is given by the equation where C is _____ J/g°C. So if the mass of water and the temperature change of the water in the coffee cup calorimeter can be measured, the quantity of energy gained or lost by the water can be calculated. Q = mwater•Cwater•ΔTwater 4.18

6. imetry Calo r 2. It is assumed that there is a heat exchange between the object under study and the _______ in the cup and that no other objects are involved in the heat exchanged. water

7. imetry Calo r

8. imetry Calo r A. Although we can get reasonable results using a coffee-cup, bomb calorimeters are used at the professional level. Bomb calorimeters provide greater _________ and _______ heat loss to the surroundings. insulation reduce
