Specific Heat                                                            

1.)Is it better to have more or less water in the calorimeter when conducting these laboratory exercises (which require the accurate measurement of the water’s temperature change)?

2.)In the course of the laboratory exercises, we assumed that no heat energy (Q) entered or left the Styrofoam calorimeter. Is this an accurate assumption? Why or why not?

3.)Indicate which material, Styrofoam or aluminum, makes the best calorimeter for use during laboratory exercises and why it is preferred.

Explanation / Answer

1) It is better to have relatively less water in the calorimeter while conducting the experiments. If the volume of the water is increased, then the rate of cooling will be slower, because there are more molecules in greater volume than less volume. Thus, it will take more time to lose the heat energy from all the molecules.
