Question

Coefficient of linear expsnsion = _×coefficient of volume expansion​

Answer 1

The change in volume ΔV is very nearly ΔV = 3αVΔT. This equation is usually written as ΔV = βVΔT, where β is the coefficient of volume expansion and β ≈ 3α. Note that the values of β in Table 1 are almost exactly equal to 3α. In general, objects will expand with increasing temperature.
