from t = t1 will it loose one fourth the total heat?
One end of rod of length L and cross-sectional area A is kept in a funrance of temperature T1. The other end of the rod is kept at at temperature T2. The thermal conductivity of the material of the rod is K and emissivity of the rod is e. It is given that T2 = TS+ΔT where ΔT<<TS, TS being the temperature of the surroundings.
