Is thermal expansion linear
WitrynaLinear Expansion Over small temperature ranges, the fractional thermal expansion of uniform linear objects is proportional the the temperature change. This fact can be used to construct thermometers based on the expansion of a thin tube of mercury or alcohol. Several equivalent forms of the relationship find use. The calculation is set up in ... Witryna13 lut 2024 · The more advanced way (and more precise way) of treating this is to express the linear expansion as d L L = α d T where dL and dT are differentials. Then by the product rule, d V = d ( h w l) = w l d h + h l d w + h w d l = h w l ( d h h + d w w + d l l) = h w l ( 3 α d T) So, d V V = 3 α d T Share Cite Improve this answer Follow
