Hey everyone, just a quick post for now. I worked over the weekend on a lab for thermodynamics on a lab where I measured the thermal expansion of three metals (copper, aluminum, and steel) and compared the measured values to the experimental values. It is actually very elementary stuff equation-wise, but interesting never-the-less. It is also interesting to point out this stuff is around us all the time. You ever see those "cracks" in the bridge? Yea, cement expands and contracts.
