## What is relation between coefficient of linear expansion and coefficient of volume expansion of a solid material?

V=Vo(1+γt)

### What is the relationship between the coefficients for linear thermal expansion and volume thermal expansion?

For isotropic materials the coefficients linear thermal expansion α and volumetric thermal expansion αV are related by αV = 3α.

#### What is the relation between co efficient of linear expansion and co efficient of superficial expansion of solid?

We know that the coefficient of linear expansion is equal to half of the coefficient of superficial expansion.

**What is meant by coefficient of cubical expansion derive the relationship between coefficient of cubical expansion and coefficient of linear expansion?**

Answer: Coefficient of linear thermal expansion : It is the change in length per unit length per unit change in temperature. Coefficient of cubical thermal expansion : It is the change in volume per unit volume per unit change in temperature.

**What is the relation between coefficient of linear expansion and area expansion?**

The relationship between the area and linear thermal expansion coefficient is given as the following: αA=2αL α A = 2 α L . Just like the linear expansion coefficient, the area thermal expansion coefficient works as an approximation over a narrow temperature interval only.

## What is the formula of coefficient of linear expansion?

Linear thermal expansion is ΔL = αLΔT, where ΔL is the change in length L, ΔT is the change in temperature, and α is the coefficient of linear expansion, which varies slightly with temperature.

### What is the coefficient of linear expansion?

The coefficient of linear expansion is the change in length of a specimen one unit long when its temperature is changed by one degree (see linear expansion). Different materials expand by different amounts. If these forces are strong, the material can only expand slightly for a given rise in temperature.

#### What is the relation between coefficient of linear expansion and coefficient of areal expansion?

**What is meant by coefficient of linear expansion and superficial expansion derive the relationship between them?**

Increase in length per unit of the length, per degree Celsius rise in temperature is called Coefficient of Linear expansion. Increase in area per unit of the original area, per degree Celsius rise in temperature is called Coefficient of Superficial expansion.

**What is coefficient of expansion?**

Definition of coefficient of expansion : the ratio of the increase of length, area, or volume of a body per degree rise in temperature to its length, area, or volume, respectively, at some specified temperature, commonly 0° C, the pressure being kept constant.

## Does the coefficient of linear expansion depends on length?

statement (1): The linear expansion does not depend on the nature of the material, initial length, and rise in temperature.

### What are the factors on which coefficient of linear expansion depends?

The amount by which it expands depends on three factors: its original length, the temperature change, and the thermal (heat) properties of the metal itself.

#### What is the relation between the coefficient of linear expansion and areal?

γ = coefficient of volume expansion. Since, coefficient of linear expansion is in one direction and areal in two dimension followed by three dimension in case of volume expansion. So, to compensate that factor the relation between them will be like.

**What is the coefficient of thermal expansion of a material?**

The relative expansion of the material divided by the change in temperature is known as the coefficient of linear thermal expansion. Do all materials have the same expansion coefficients?

**What is the relationship between volume expansion and length expansion?**

α = length expansion coefficient, ΔT = temperature difference, ΔL = change in length. Volume expansion occurs when there is a change in volume due to temperature.

## What is the formula for linear expansion?

Linear expansion is the change in length due to heat. Linear expansion formula is given as, frac {Delta L} {L_ {o}}=alpha _ {L}Delta T. Where, L0 = original length, L = expanded length, α = length expansion coefficient, ΔT = temperature difference, ΔL = change in length.
