An electronic device, such as a power transistor mounted on a finned heat sink, can be modeled as a spatially isothermal object with internal heat generation and an external convection resistance. Consider such a system of mass, 0.38 kg, specific heat, 450 J/kg*K, and surface area, 220 cm2, which is initially in equilibrium with the environment at 29 C and 65 W/m2*K. Suddenly, the electronic device is energized such that a constant heat generation, 100 W occurs. If the device is initially at 29 C, what temperature will it reach 6.00 min after the power is switched on?
