I want to know how to find delta T and if the coefficient of linear expansion is calculated by dividing delta L and the initial length of object (Lo) and delta T?

Respuesta :

[tex]\Delta L=\propto L_{\circ}\Delta T[/tex]

Therefore,

[tex]\begin{gathered} \Delta T=100^{\circ}-23^{\circ}=77^{\circ} \\ \Delta L=0.001m \\ L_{\circ}=0.601m \end{gathered}[/tex][tex]\begin{gathered} \propto=\frac{0.001}{0.601\times77} \\ \propto=\frac{0.001}{46.277} \\ \propto=0.000021609^{\circ}C^{-1} \end{gathered}[/tex]
