Heat is produced within a solid sphere with a radius of 0.65cm with a heat conductivity of 58W/m.K. The amount of heat produced per unit volume and per unit time is given as Q(W/m3s)=6.2103T0.6 where T is the temperature (K). The surface temperature of the sphere is 106C. a) Write the energy balance on the solid sphere. b) Solve the energy balance with MATLAB to obtain the temperature profile within the sphere cable by appropriate assumptions
