17.62 . A long rod insulated to prevent heat loss along its sides is in perfect thermal contact with boiling water (at atmospheric pressure) at one end and with an ice–water mixture at the other (Fig. E17.62). The rod consists of a 1.00-m section of copper (one end in boiling water) joined end to end to a length L2 of steel (one end in the ice–water mixture). Both sections of the rod have crosssectional areas of 4.00 cm2. The temperature of the copper–steel junction is 65.0_C after a steady state has been set up. (a) How much heat per second flows from the boiling water to the ice– water mixture? (b) What is the length L2 of the steel section?

I have not created a lesson for this question yet.

Please leave a comment below with specifics about the question, and I will make a detailed lesson on it as soon as possible. (I can usually have something up within a day.)

NEED IMMEDIATE HELP? Get the student solution manual here: University Physics Manual otherwise, I should be able to get a video lesson up within a day or so.
