One end of an iron poker is placed in a fire where the temperature is 493 °C, and the other end is kept at a temperature of 22.2 °C. The poker is 0.977 m long and has a radius of 4.59 × 10-3 m. Ignoring the heat lost along the length of the poker, find the amount of heat conducted from one end of the poker to the other in 7.00 s. Take the thermal conductivity of iron to be 79 J/(s m Co).
