A silver bar 0.125 meter long is subjected to a temperature change from 200°C to 100°C. What will be the length of the bar after the temperature change

Respuesta :

     Using the Equation of Linear Expansion, we have:

[tex]\Delta L =L_{o}. \alpha .\Delta T \\ L-L_{o}=0,125.19.10^{-6}.(200-100) \\ L=2,375.10^{-6}.10^2+0,125 \\ \boxed {L=0,1252375m}[/tex]
