A vertical glass tube of length L = 1.2800000 is half-filled with a liquid at 20.0000* C. How much will the height of the liquid column change when the tube is heated to 30.0000*C?
Glass linear expansion co = 1e-5/K
Liquid volume expansion co = 4e-5/K
I don't really understand why I'm not given the dimensions of the tube that matter IE radius. The only purpose of knowing the length is knowing the initial height of the liquid. The expansion of the length of the tube won't effect how the height of the liquid changes... but the expansion of the tube's "insidey part" certainly does... which I know nothing about!
