what is coefficient of volume expansion for liquids. The theory of similarity and the molecular characteristics of the materials serve as the basis for the derivation of quantitative relationships. This equation shows the relationship between a is the linear expansion v is the superficial expansion is volume expansion.

It generally measures the fractional change in the size of the object with the change in the temperature keeping the pressure constant. Expansion Coefficient also known as coefficient of thermal expansion is the change in the size of an object could be solid liquid or in gaseous state with the rate of change in the temperature. What volume of radiator fluid will overflow when the radiator and fluid reach their 950oC.
DV a v DT V 0 where DV is the change in volume a v is the volumetric coefficient of expansion DT is the change in temperature from the initial temperature associated with V 0 the initial volume.
There are many recorded values for a v depending on the substance. These three coefficients of expansion for a given solid are not constant because these values totally depend on the temperature. Since a is a constant unknown coefficient it can be said that 3a is a new constant unknown coefficient named the coefficient of volume thermal expansion v. Volumetric expansion coefficients for commonly used liquids.
