Question

The equation you found in the previous activity be turned into can and equality by inserting an unknown constant c. Q alpha m Delta T Becomes Q = m Delta T Solve the equation symbolically for the unknown constant c. C = Q/m Delta T This constant is given name specific heat. Recall that each pulse, activated the heater for 5 s. Using the data that you collected in the lab and the power rating of the heater. fill in table 3. What are the possible source of experimental error that might explain any difference in your results? The answer human error. Instrument calibration will not receive any credit (If you did indeed have any of these you needed to correct them otherwise the experiment has no value to anyone). If the heater were plugged directly into a well outlet so that it was on continuously, how many minutes would it take to raise the department of 300g of water by 25degree C? Show your calculation. (Use C_water = 4190 J/kg degree C)

Explanation / Answer

1) Loss of energy due to evaporation.

2) Energy added by stirring.

3) Unequal stirring during between trials.

4) Different starting temperatures of water.

5) Loss of energy through the cup into the air and table.

6) temperature of water not uniform (water not properly stirred)
