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 met

Readme [11.4K]

Answer:

0.000225 m

Explanation:

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

Length = 0.3 meters

ΔT = Change in temperature = 250 °C

Linear expansion

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

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