(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A steel ball bearing is encased in a Pyrex glass cube 1.0 cm on a side. At 390K , the ball bearing fits tightly inside the cube.

At what temperature will it have a clearance of 0.90pico meters all around?

2. Relevant equations

Coefficent of linear expansion:

[tex]\propto[/tex] =(Change in L / L) / change in T

Im not sure what my Delta L should be.....

L= .01 m

T initial is 390K

the [tex]\propto[/tex] is 3.2e-6

3. The attempt at a solution

I just need delta L in order to solve for T final
