What is the relation between the coefficient of linear and superficial and volume expansion respectively?

The coefficient of linear expansion (α) is one-third of the coefficient of superficial expansion (β), and the coefficient of superficial expansion is one-third of the coefficient of volume expansion (γ). This relationship follows from the dimensional analysis of the expansion coefficients in the respective directions.


What is meant by the cofficient of linear and superficial expansion?

The coefficient of linear expansion measures how much a material expands in length when heated, while the coefficient of superficial expansion measures how much a material expands in area when heated. Both coefficients are used to quantify how materials respond to changes in temperature.


What is superficial expansion?

Superficial expansion is the increase in surface area of 1 meter square area of a solid for rise of temperature, 1kelvin is called the coefficient of surface expansion of material of that solid.


A material has a coefficient of volume expansion of 60×10^-6/degree celsius. What is its coefficient of expansion?

The coefficient of volume expansion is the triple of the linear expansion coefficient. So with a volume expansion coefficient of 60×10^-6/°C, the linear expansion coefficient would be 20×10^-6/°C.


Why liquids have two coefficient of expansion?

Liquids have two coefficients of expansion because they can expand in both volume (volume coefficient of expansion) and in area (area coefficient of expansion) when heated. The volume coefficient of expansion relates to changes in the volume of the liquid, while the area coefficient of expansion relates to changes in the surface area.

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.

What is the coefficient of thermal expansion of air?

The coefficient of thermal expansion of air is approximately 0.00367 per degree 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.
