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
1.066 mm = .001066 m
Change in Temp = 99.5 - 21.7 = 77.8 C1
Coefficient = (.001066) / (.006736 * 77.8 ) = 0.002034 = 2.034 x 10^-4
My units are all in meters and degrees C, but my coefficient is off. It should be in the area of 10^-6 not 10^-4. The measurements are taken from a lab we performed and the rod was solid not a gas or liquid. Help?
