Steel has an expansion coefficient nearly equal to that of modern concrete.
It will have a table containing thermal expansion coefficients for various metals.
The above example assumes that the expansion coefficient did not change as the temperature changed.
At exactly 3.98 degrees C, the thermal expansion coefficient of water is actually zero.
You will have to figure out your most useful way to think about this variable expansion coefficient.
In addition, the difference of their thermal expansion coefficient is also small.
Subsequent measurements by other groups were however not able to reproduce their results, but rather found expansion coefficients similar to copper.
Probably the expansion coefficient differs in this rain forest enough to make even properly set felt slip.
Strong bonds result in higher melting temperatures and lower thermal expansion coefficients.
I have suggested that the Commission include an expansion coefficient in their calculations.
