Electrical equivalent of Heat
-
If water was replaced with, say propane, would you still use it for calculating the Joule-
Calorie
conversion?
-
If the heating is done too fast, will the slope be still linearly increasing according to
Joule’s
electric heating formula?
-
How long from the original starting time would it have taken to achieve a temperature of 500C
with
experimental arrangement you used?
-
Assuming that one used the same heating coil and that its resistance did not change, how much
would
the power be increased if the voltage were increased by 50%?
-
Suppose that some liquid other than water were used in the calorimeter. If liquid had a specific
heat of 0.25cal/ºCg, would that tend to improve the results, make them worse or have no effect
on
them?
-
What does the slope of the fit to graph A represent?
The temperature of the part of the thermometer that is immersed in water also increases? But
this
rise is not accounted for in the calculations. To what extent this affects the result?

How to perform the experiment, so that radiation correction is not needed?
