However, for questions one and two you will need to do some internet research. You will need to
find various quantities for the materials in question i.e. thermal expansion coefficients, specific
heats, melting points and colors at a specific temperature. (Notes: a. Pay attention to the units
that you find for the numbers. b. There may be many types of the materials listed below so pick
the values that seem appropriate to you. There is no one right answer).
