By what length will a slab of concrete that is originally 18 m long contract when the temperature drops from 24°C to -16°C? The coefficient of linear thermal expansion for this concrete is 1.0 × 10-5 C-1.

Step-by-step explanation:

According to Thermal Expansion of solids:

$dl = \alpha * l * dt$

$dl = {10}^( - 5) * 18 * 40$

$dl = 7.2 * {10}^( - 3)$
