what is the volume thermal expansion coefficient. Knowing the initial volume V 0 m 3 of a given solid the temperature difference DT oC and the coefficient of linear expansion of the solid a 1oC the change in volume DV m 3 of the solid can be calculated as. 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.
Linear Thermal Expansion Coefficient Values for Aluminum Alloys. Knowing the initial volume V 0 m 3 of a given solid the temperature difference DT oC and the coefficient of linear expansion of the solid a 1oC the change in volume DV m 3 of the solid can be calculated as. The volumetric thermal expansion coefficient is the most basic thermal expansion coefficient.
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 Thermal Expansion is calculated in a very similar fashion to Linear expansion only with measurements of volume not length. Illustrates that in general substances expand or contract when their temperature changes with expansion or contraction occurring in all directions. Over small temperature ranges the thermal expansion of uniform linear objects is proportional to temperature change.
