Thermal expansion is the way most materials get bigger when they are heated and smaller when they cool: the atoms jiggle harder and sit a little further apart. In this livestream Q/A, MES looks at what thermal expansion is, how much things grow, and why bridges, rails and pipes need room to move.
If you have math or science related questions, I may have answers!
