An assembly consisting of a heater with capacitance C1 and surface area A1 is surrounded by a box having capacitance C2 and surface area A2. The box is initially at a uniform temperature To. The heater, which supplies heat
at a rate q, is turned on and remains on until the surrounding box temperature reaches a value Toff. The heater
then switches off until the box temperature lowers to Ton and then switches on again. Determine the temperature
response of the box and the heater status vs. time. Figure 159.1 Temperature-controlled Heater Problem Sketch Material Properties
