Newton's Law for conduction of heat says that dT = k(Te – T) for some constant k > 0. dt Suppose that when the external temperature (T.) is 9 degrees higher than the internal temperature (T), the internal temperature is changing at 1 degrees per second. Find the rate that the internal temperature is changing when the external temperature is 13 degrees higher than the internal temperature. Find the rate that the internal temperature is changing when the external temperature is 13 degrees lower than the internal temperature. Find the rate that the internal temperature is changing when the internal and external temperatures are equal.
