I understand I use the equation alpha*Length*delta(t) but it won't pop out the right answer and I think the dimensions are what is throwing me off. Any advice is appreciated!

Yes, but don't forget that that's theSo, my final equation would be (9e-6)(4000)(65.556) ??

If the entire glass expands by 2.36, how much space do you have to allow at **each **end?

the given dimensions + expansion value.

delta L = alpha*Lo*delta t and that should be your answer.

Good catch! (I wasn't paying attention when the OP did the conversion. :uhh:)the error that you made was that the temp that is given is a (delta t). to convert from F to C it is just (delta t)*(5/9).... you dont subtract 32.

Fix that conversion. You're converting a temperatureI did not change to degrees Celsius. The conversion is (5/9)*(150-32) so my new temp is 65.556.
