A solid volume is $1000 c m^{3}$ at 20°C and $1016.2 c m^{3}$ at 320°C. Its linear expansion coefficient is:

Options:

Answer:

Solution:

$γ = \frac{16.2}{1000 ( 300 )} = 5.4 \times 1 0^{- 5}^{\circ} C^{- 1}$ . For isotropic first-order expansion, $α = \frac{γ}{3} = 18 \times 1 0^{- 6}^{\circ} C^{- 1}$ .
