e) One end of an iron poker is placed in a fire where the temperature is 450 °C, and the other end is kept at a temperature of 24 °C. The poker is 1.2 m long and has a radius of 5 mm. Ignoring the heat lost in convection along the length of the poker, find the amount of heat conducted from one end of the poker to the other in 5 s. The thermal conductivity of the iron is 79 W/mK
