Concept explainers
According to Stefan’s law of radiation the absolute temperature T of a body cooling in a medium at constant absolute temperature Tm is given by
where k is a constant. Stefan’s law can be used over a greater temperature range than Newton’s law of cooling.
(a) Solve the differential equation.
(b) Show that when T − Tm is small in comparison to Tm then Newton's law of cooling approximates Stefan’s law. [Hint: Think binomial series of the right-hand side of the DE.]

- According to the solution in Exercise 58 of the differential equation for Newtons law of cooling, what happens to the temperature of an object after it has been in a surrounding medium with constant temperature for a long period of time? How well does this agree with reality?arrow_forwardPlant Growth Researchers have found that the probability P that a plant will grow to radius R can be described by the differential equation dPdR=4DRP2 where D is the density of the plants in an area.
