Linear ExpansionEasyQuestion 30821

Question

Coefficient of linear expansion α is defined as:
  1. A
    ΔL/L₀
  2. B
    ΔL/(L₀ΔT)
    Correct
  3. C
    L₀ΔT/ΔL
  4. D
    ΔL × ΔT / L₀

Correct answer

ΔL/(L₀ΔT)

Explanation

α = ΔL/(L₀ΔT). It tells how much a unit length expands per degree rise.
