Information
This is a model of an electric kettle used for heating water. The heating circuit is controlled by a thermostat and a timer.
Model Calibration
Using Mathematica, fit the parameters for the resistor and the heat loss to measurement data.
Simulation Analysis
Simulate the system and see a plot of its behavior. Click the Simulate button: 
A plot showing the behavior for the system can now be seen:
The control has a timer that keeps the temperature around 99 °C for 10 minutes.
