# Heat Conduction

Classical Mechanics Level pending

A 90.0 cm wire with a diameter of 1.55 mm is perfectly insulated at its sides. Such that a fire is lighted at the head end with a constant temperature of 368 K, while the temperature at the other end is 285 K. If the thermal conductivity of the wire is 380 W $${ m }^{ -1 }{ K }^{ -1 }$$, what is the rate of heat flow along the wire in Watt?
