Homework Help: Physics

Posted by Lynn on Monday, June 13, 2011 at 10:03pm.

In my lab of linear expansion, I need to find out the coefficient of linear expansion. The data I got for an aluminum rod are initial length is 59.7cm, the change in length is 95mm, the change in temperature is 75.4 Celsius degrees. I converted 59.7cm to 0.597m, and 95mm to 0.095m. But I got no where near the standard coefficient of linear expansion for aluminum, which is 22.5*10^-6, how come????????



PLEASE HELP!!!!!!!THANKS A LOT!!!!!!!!!
