Discover Physics with free Physics Revision Notes and Physics Calculator: Thermal Expansion. This image shows the properties and thermal expansion formula for the Thermal Expansion. The Thermal Expansion Calculator will calculate the linear expansion or contraction of a bar of original length, the Area expansion or contraction of a thin plate of original area and the Volume expansion or contraction of a solid object of original volume

Final length of the bar Formula and Calculation

L = L₀ × 1 + α × ( T - T₀ )

Final area of the plate Formula and Calculation

A = A₀ × 1 + 2α × ( T - T₀ )

Final volume of the object Formula and Calculation

V = V₀ × 1 + 3α × ( T - T₀ )

Remark! You can find the amount of expansion or contraction Δ in each case by subtracting the original value from the final one. Thus,

∆L = L - L₀
∆A = A - A₀
∆V = V - V₀

If Δ > 0 , there is thermal expansion and if Δ < 0 , there is thermal contraction in the material.
