Welcome to PHY 121 Blog Help. Here's how it works. For each homework question and lab report we will make a post, this will probably contain a few tips on what the problems are about and how to solve them. If you are stuck on something then instead of emailing us directly you should post a comment in reply to the relevant post. We will try to guide you through tough points and help you understand the problems and the concepts behind them.

anyone know what to use for alpha?
alpha of mercury is 140 J/kgK
My deltaL is 0.71mm = 710m
from 22 C to 35 C. I solved and got 0.39 for L0 but it says it's wrong? Help please?
my numbers were 22 degrees C, 35 degress C, and .79mm. So i did 140*13 all divided by 790 and what did i do wrong?
0.71 mm is 0.00071 m
and alpha you need to use is for steel and not for mercury there is no mention of mercury
