Bob who is working on a glacier wants to experiment with heat andhas constructed a two part metal rod. The left rod is silver andhas length L1 = .5454 M, and has a cross sectional area A = 3.1416CM^2. It is joined end to end with a lead rod of identical diameterand length L2 = .3554 M. Bob has insulated the curved surface,placed the left end in a pot of boiling water and the right end ina hole in the glacier. After thermodynamic equilibrium has beenachieved, there is a puddle of water in the glacier and theassumption that the right end is at a temperature T1 = 0.00 degC.

1) Calculate the heat flow per second through the rod.

2) Calculate the temperature, T2, at the interface between the tworods.

3) Calculate the change in entropy of the teapot in one second.

4) Calculate the change in entropy of the glacier in onesecond.

5) Calculate the change in entropy of the universe in onesecond.
