1. Before I add water to either of the beakers what do you think the temperature would be at various points along the rod ?

2. Please draw a graph of the temperature you have estimated versus the length along the rod.
   
   

3. Please write one or two sentences explaining why you think the temperature profile you have drawn is correct.

4. Explanation.

5. What do you think the temperature along the rod would be immediately after I add boiling water to one beaker and ice water to the other ?

6. Please draw a graph of your prediction of the temperature along the rod immediately after I have added boiling water to one beaker and ice water to the other.
   
   

7. Also draw a graph of the temperature along the rod for a time much later.

8. Please write one or two sentences explaining why you think the temperature profiles you have drawn are correct.

9. Please draw the temperature observed immediately after I added the water to the two beakers.
   
   

10. On the same graph as Q9 please draw the temperature observed now that the system has come to a steady state situation.

11. Explanation.

12. In the demonstration just completed I placed some insulation along the bar before I added water to the beakers. What role does the insulation perform in this experiment?

13. If I don't use the insulation and repeat the experiment adding ice water to one beaker and boiling water to the other beaker what do you think the temperature profile along the rod would look like this time after it has come to a steady state situation ? Please draw your prediction.
    
    

14. Explanation.
