A long rod, insulated to prevent heat loss along its sides, is in perfect thermal contact with boiling water (at atmospheric pre

ssure) at one end and with an ice-water mixture at the other (Figure 1). The rod consists of 1.00 m section of copper (one end in steam) joined end-to-end to a length L2 of steel (one end in ice). Both sections of the rod have cross-section areas of 4.00 cm2. The temperature of the copper-steel junction is 65.0∘C after a steady state has been set up. How much heat per second flows from the steam bath to the ice-water mixture?

Heat per second flows from the steam bath to the ice-water mixture is

H= 5.39 W.

This is further explained below.

<h3> How much heat per second flows from the steam bath to the ice-water mixture?</h3>

Generally, The term "heat" refers to the energy that is transferred from one body to another as a direct consequence of a temperature differential.

When two bodies with different temperatures are brought together, energy will transfer, also known as heat flow, from the body with the higher temperature to the one with the lower temperature.

In conclusion, The heat traveling through the copper rod

H = K*A*dT/l

H = 385*0.0004*35/1

H= 5.39 W.

The steel will conduct heat at the same rate across its whole.
