Question: A long steel rod, insulated to prevent heat losses, has one end immersed in boiling water (at atmospheric pressure) and the other end in a water-ice mixture. If the steal rod is 100cm long and area of 5cm2, after establishing a steady state condition, how much heat per second is transferred from the steam bat to the ice- water mixture? (k for steal = 50J(sm0c)-1?
Answer: 2.5Watt
