What are the two types of thermal expansion?
Linear expansion and volumetric expansion are the two types of thermal expansion. Linear expansion is the increase in length of a material when heated, while volumetric expansion refers to the increase in volume of a material when heated.
What is thermal expansion and explain its two types?
Thermal expansion is the tendency of a material to change in volume, length, or area in response to a change in temperature. The two main types of thermal expansion are linear expansion, where an object grows in length in one dimension, and volumetric expansion, where an object expands in all dimensions.
What is the coefficient of linear expansion of mercury?
-39 degrees celsius to 450 degrees celsius
What is the relationship of coefficient linear expansion to actual expansion?
The coefficient of linear expansion is a constant value that quantifies how much a material expands per degree Celsius increase in temperature. The actual expansion of an object can be calculated by multiplying the coefficient of linear expansion by the original length of the object and the temperature change.
Linear expansion apparatus?
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..
What are the applications of linear expansion?
Invar (a special iron - nickel alloy) is used in pendulam instead of aluminium ,in order to decrease the expansivity.

What is linear expansion?
If a body is heated and after heating the body if the expand in one dimension then it is called linear expansion

Does the coefficient of linear expansion depends upon length?
yes,according to relation coefficient of linear expansion depends upon original length.
Does the linear programming approach apply the same way in different applications?
Linear programming approach does not apply the same way in different applications. In some advanced applications, the equations used for linear programming are quite complex.

What is the cubical coefficient of thermal expansion for metals?
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.
Does coefficient of linear expansion depend on length?
No, the coefficient of linear expansion does not depend on the initial length of the material. It is a material property that remains constant regardless of the length.
As the temperature increases materials with large coefficients of linear expansion increase a lot in size while materials with small coefficients of linear expansion increase a in size?
Large
