1. In your own words, what is the difference between heat and temperature?
2. Why does the amount of heat lost by the copper have to equal the amount of heat gained by the water and the calorimeter?
3. Why do the temperatures have to be extrapolated to the time of mixing?
4. A student carried out an experiment similar to this one. lie found the temperature of the boiling water bath to be 100.7°C. Iron pieces weighing 51.70g were placed in a test tube and heated in the boiling water bath for 10 minutes. 50.0mL of water were placed in the calorimeter and the temperature was measured every 30 seconds for 4 minutes. The hot iron was dumped into the calorimeter and the readings were continued until a constant downward trend had been established. When the student extrapolated the temperatures to the mixing time, he found that the water started at 22.2°C and ended up at 29.4°C.
5. In order to calculate the heat gained by the water and the calorimeter, what are the initial and final temperatures used?
T1water ___________
T2water ___________
6. In order to calculate the heat gained by the water, what is the mass of the water to be used?
Masswater ___________
7. In order to calculate the heat lost by the iron, what are the initial and final temperatures to be used?
T1iron ___________
T2iron ___________
8. Calculate the specific heat of the iron used in this experiment. Show all calculations.
Specific Heat of Iron ___________.
