Reference no: EM13305641

A copper bar 2.5 m long has a circular cross section of radius 2 cm. One end is kept at 80oC and the other end is kept at 0oC. The surface of the bar is insulated so that there is negligible heat loss through it. If kcopper = 401 W.m-1.K-1, what is the temperature gradient along the length of the bar?
