Why would they expand? Things contract when they get colder.

Not everything.

not always. ice water is less dense than liquid water

That's because it forms big crystals, not because colder water is less dense than warmer water.

Is this some sort of crazy mechanical engineering question?
Do you know how elasticity changes with temperature?

If I have gum in my mouth and take a drink of cold water, the gum gets hard. So I would think that elasticity would go down with temperature.

thermodynamics question.
if I say dE = dQ - dW...and say dQ = 0 since it's adiabatic, I get
dE = -dW = -pdV = dTc_v
but since it's tension and length I'm dealing with
FdL = dTc_v
so expansion when the temperature increases, contraction when the temperature decreases
I just need to know if this is actually what happens...otherwise I screwed up somewhere

Water is most dense at 4 C.
