Heat Flow Analysis

Answer the following questions in Notes on your handheld computer.

  1. While mixing water at two temperatures, did the result match your prediction? If they differed, why? Derive a formula for the final temperature when you mix equal amounts of different temperatures of water.

  2. Which exchanged heat faster, the water mixed together or the clay in the water? Why?

  3. Draw the resulting graph of the clay temperature as it approaches the temperature of the water. Why do you think it has that shape?

  4. Do you think the shape of the clay makes a difference in the results? Give examples of other shapes besides a ball that you could use and how they would behave differently.

  5. How did your method of insulation compare to methods used by others? Explain why the differences occurred.
