Calculate the change in length of a Pyrex glass dish (Coefficient of linear expansion for Pyrex is 3 x 10^-6 /C) that is 0.3 meters that undergoes a temperature change of 250 C.

Respuesta :

Answer:

0.000225 m

Explanation:

Coefficient of linear expansion = [tex]\alpha_L=3\times 10^{-6} /C[/tex]

Length = 0.3 meters

ΔT = Change in temperature = 250 °C

Linear expansion

[tex]\frac{\Delta L}{L} = \alpha_L\Delta T\\\Rightarrow \Delta L=\alpha_L\Delta T\times L\\\Rightarrow \Delta L=3\times 10^{-6}\times 0.3\times 250=0.000225\ m[/tex]

Change in length of the Pyrex glass dish is 0.000225 m.
