Question

Quizplus · Accepted Answer

The rate of heat transfer in conduction, convection, and radiation is dependent on the area exposed. In conduction and convection, heat transfer directly involves the area through which heat is being transferred. In radiation, the emitted or absorbed heat is proportional to the surface area of the emitting or absorbing body, according to the Stefan-Boltzmann law.
