Result of the second calorimetry test run. You can almost see the exponential shape in the quasi-linear curve during DC heating, but the experiment needs to run for longer to reveal its full shape. Also, the motorized stirrer creates a considerable amount of excess heat, as seen from the calorimeter's inability to settle at the original equilibrium unless the motor is switched off. I may need to mount the motor farther from the calorimeter and run it at a lower speed... #electronics
