Section 1: Units and Measurements

L = L_{0} × 1 + α × ( T - T_{0} )

A = A_{0} × 1 + 2α × ( T - T_{0} )

V = V_{0} × 1 + 3α × ( T - T_{0} )

**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 - L_{0}

∆A = A - A_{0}

∆V = V - V_{0}

∆A = A - A

∆V = V - V

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