Heat capacity of a cup & stirrer

Let's consider how the combined heat capacity of the cup and stirring bar affects the calibration of the light bulb or laser.

[ Another issue to be considered are evaporative losses from the cup surface. Some experiments were done (not shown here) to demonstrate that the effect of such evaporative losses on this experiment are minor if the temperature rise is only a few degrees.]
