How do you calculate coefficient of linear expansion of copper?

Answer 1

dL/dT = αL*L, where L is the length of the steel, T is temperature, and αL is the linear thermal expansion coefficient which for steel is about 11.0 to 13.0.

That is possibly the easiest differential equation in history:

(1/L)dL = (αL)dT

ln(L) = αLT

L = eαLT

Answer 2

CoTE( Coefficient of Thermal Expansion)= [Change in dimension]/[Original Dimension x Change in Temperature]

Here

Dimension implies Length,Volume,Surface Area etc.

And Change in Dimension implies Change in Length,Change in Volume or Change in Surface Area etc.

For every dimension the symbol of Coefficient of Thermal Expansion is different.

For example Coefficient of Linear Expansion is represented by Alpha

Coefficient of Linear Expansion is represented by Beta

RELATIONS BETWEEN CoTE's

Beta=3(Alpha)

Coefficient of two dimensional expansion(Surface Area Expansion)=2(Alpha).

Answer 3

It depends upon the humidity, temperature, type, thickness, density and surface area to volume ratio of the wood

Answer 4

You would have to measure the size of a sample, at different temperatures.

Answer 5

10 into 10-6 per degree Celsius
