What is the relationship between linear and cubic expansivity?

Linear expansivity is the increase in length per unit length per degree rise in temperature. While cubic expansivity is the increase in volume per unit in volume per degree rise in temperature.


What is coefficient of cubical expansivity?

The coefficient of cubical expansivity would normally be the cube of the coefficient of linear expansivity unless that coefficient is different in different directions for a material. In that case it would be the product of the linear coefficients in the different directions.

What is the term linear expansivity?

It is defined as close in temperature of substance


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.


Iron has linear expansivity of 0.000012k brass has a linear expansivity of 0.000019k . draw diagrams to show what will happen to a bimetal strip made from ironand brass if it is heated or cooled.?

It is easier to open because the hot water is like fire. So the cap is not strong to hold the hot water. becouse the top expands befour the heat reaches the bottle which makes it a looser fit


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.

How many hectar are 320 meters?

You can't convert that. You can convert from one linear unit to another linear unit, or from one square unit to another square unit, but not between linear units and square units.
