Question

Volumetric Thermal Expansion Formula​

Answer 1

Answer:

The change in volume ΔV is very nearly ΔV = 3αVΔT. This equation is usually written as ΔV = βVΔT, where β is the coefficient of volume expansion and β ≈ 3α. Note that the values of β in Table 1 are almost exactly equal to 3α. In general, objects will expand with increasing temperature.

For a solid, we can ignore the effects of pressure on the material, thus the volumetric thermal expansion coefficient can be written: αV=1VdVdT α V = 1 V dV dT , where V is the volume of the material, and is dV/dT the rate of change of that volume with temperature.
