QUESTIONS 1) Why is it important in this experiment that the final temperature be as much above room temperature as the beginning temperature was below? 2) How would the computed value of the specific heat be affected if some of the boiling water were carried over with the sample? 3) How would the computed value of the specific heat be affected if it took you one minute to shake the water from the sample? 4) Your lab partner is a klutz and drops the heated sample onto the floor. Being in a hurry, you decide to continue with the experiment. Do you expect your computed value for the specific heat to be too high or too low? 5) When you determine the specific heat of a sample, you start with a water temperature that is 3°C below room temperature. The equilibrium temperature turns out to be only 1 C above room temperature. How will this affect your value? 6) After you finish measuring the specific heat of your unknown, you discover that it is hollow. Would you need to correct for this? If so, how?Explanation / Answer
11.
heat gained or lost is given as
Q = m c deltaT
let the temperature of furnace be T
then using conservation of energy
Heat lost by platinum ball = heat gained by water
(100) (0.33) (T - 10) = 400 (1) (10 - 0 )
T = 131.2
