Performance Task
20.
You have been tasked with designing a baking pan that will bake batter the fastest. There are four materials available for you to test.
- Four pans of similar design, consisting of aluminum, iron (steel), copper, and glass
- Oven or similar heating source
- Device for measuring high temperatures
- Balance for measuring mass
Instructions
Procedure
- Design a safe experiment to test the specific heat of each material (i.e., no extreme temperatures should be used)
- Write down the materials needed for your experiment and the procedure you will follow. Make sure that you include every detail, so that the experiment can be repeated by others.
- Carry out the experiment and record any data collected.
- Review your results and make a recommendation as to which metal should be used for the pan.
- What physical quantities do you need to measure to determine the specific heats for the different materials?
- How does the glass differ from the metals in terms of thermal properties?
- What are your sources of error?
