No dice. With the change in length set at 0.066 mm, the co-efficient is still only 1.259 x 10^-4. Two orders of magnitude too high.

I'm not sure what you meant haruspex, changing the leading digit didn't change the magnitude only the leading value. The coefficient changed from 2.034 x 10^-3 to 4.623x 10^-3 or 3.942 x 10^-3. Recorded Values Hypothesis 1 Hypothesis 2 Original Length 6.736 mm Original Length 5.736 mm...

I was leaning towards aluminum because it had the closest co-efficient and I figured I was messing up the units someplace. I guess my lab group read the micrometer wrong.

Homework Statement Original Length = 6.736 mm Final Length = 7.802 mm Initial Temp = 21.7 C Final Temp = 99.5 C Homework Equations Coefficient = (Change in Length) / (Original Length * Change in Temperature) The Attempt at a Solution Change in Length = 7.802 - 6.736 = 1.066 mm...
