Homework Help: science

Posted by Mirayah Robinson on Wednesday, August 17, 2005 at 4:58pm.

What is the length of an aluminum rod at 65 degrees celcius if its length at 15 degrees celcius is 1.2 meters? My choices are A.0.001386 meters, B.0.00180 meters, C.1.201386 meters, or D. 1.214855 meters. I already sent this question to you about a month ago, but the equation given didn't work, so could someone else help me. Thank You.


The coefficent of linear expansion for aluminum is 23.0 x 10-6/°C.

New length= old length (1+coefficent*(65-15))
New Length= 1.2 (1+ 23.0 x 10-6/°C*50)

One of the answers is correct.


the answers is C.
