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

A rod is measured to be exactly 21.02 cm long using a steel ruler at a temperature of 21.1oC. Both the rod and the ruler are placed in an oven with a temperature of 340.0oC where the rod now measures 21.32 cm using the same ruler. What is the coefficient of thermal expansion for the material of which the rod is made?

2. Relevant equations

deltaL=L*alpha*deltaT

deltaL=Change in length

alpha=linear thermal expansion coefficient

deltaT= change in temperature

3. The attempt at a solution

I'm not sure how to solve for alpha of the rod =/
