-39 degrees celsius to 450 degrees celsius
the linear expansion of gold is 14.3*10^-5
Linear expansion apparatus is the apparatus used to measure the objects to these following properties: -> coefficient linear expansion -> coefficient thermal expansion -> specific gravity -> specific heat -> thermal conductivity -> thermal resistivity -> breaking strength and many others..
By knowing the coefficient of linear expansion of solids, you can determine how a solid reacts to temperature. Everything reacts to thermal expansion. For instance, a concrete bridge expands when hot, and with the formula for expansion and the coefficient for it, you know just how much that concrete expands and you can plan and build accordingly. That saves lives.
The coefficient of linear expansion DOES not depend on the length. Each material has a certain value for its coeeficient of linear expansion. The length of the material dictates how much it will expand linearly for a given rise in temperature. L" = L'(1 + a x (T'' - T')) That is the length at temperature T'' which is higher than temperature T' is given by the length L' at temperature T' multiplied by the quantity [1 + a x (T" - T')], where a is the coefficient of linear expansion which is constant for a given material. Thus if the temperature difference T" - T' is large then the expansion will be large which means L" - L' will be large. Likewise if the original length L' is large, then the corresponding expanded length L" will be large
Road has larger coefficient of linear expansion
The coefficient of superficial expansion refers to the ratio of change in area to an increase in its temperature. It measures the expansion of a Laminar surface.
Since most metals are isotropic, the cubical coefficient of expansion is three times the linear coefficient of expansion. The linear coefficient of expansion is obtained from measurement and tables for the specific material which are readily available.
yes,according to relation coefficient of linear expansion depends upon original length.

Thermal expanasion coefficient fro monel is 0,0000075 m/mºC. More info at http://www.engineeringtoolbox.com/linear-expansion-coefficients-d_95.html
The tracks have a larger coefficient of linear expansion than the ground beneath.
The thermal expansion of mercury is proportional and linear to temperature.

Because the two metals have different coefficient of linear expansion
Freezing water will expand about 3% linearly as it freezes, then it will contract with a positive expansion coefficient as ice and gets colder. It can be measured using methods such as dilatometer or transducer.
