What is coefficient of cubical expansivity?

The coefficient of cubical expansivity is a measure of how the volume of a substance changes with temperature. It is defined as three times the linear coefficient of thermal expansion. It is denoted by the symbol β and has units of K^-1.


Does the cubical expansivity of a liquid depend on its original volume?

No. The expansivity is on a per unit basis just like the specific heat or density is.


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.


How do you know the expansivity of a bimetallic strip?

You can test the bimetallic strip's expansivity by placing it in a hot or cold environment, such as a refrigerator or a Bunsen burner. The strip that contracts or expands more has a higher expansivity than the other.
