Common questions
What is the Volume Thermal Expansion formula?
Volume Thermal Expansion is written ΔV = βV₀ ΔT. Change in volume due to temperature change. It belongs to Thermodynamics, under Heat & Temperature.
What are the units in ΔV = βV₀ ΔT?
In SI units, ΔV is change in volume, measured in m³; β is volume expansion coeff, measured in 1/K; V₀ is original volume, measured in m³; ΔT is temperature change, measured in K.
How is the Volume Thermal Expansion formula derived?
For isotropic materials, β ≈ 3α. The result is ΔV = βV₀ ΔT.
