So I've been working at a steel mill where we deal with billets cooling from temperatures around 1200 C to between 10-25 C. I have access to average thermal expansion coefficients over this temperature range.
First question: Over a large temperature range as aforementioned am I correct in assuming it is better to integrate the thermal expansion formula rather than taking an average value for the thermal expansion coefficient?
Second question: When integrating the thermal expansion formula am I correct in assuming (as is usually the case) that I should use temperatures in Kelvin?
