WebHow to quantify thermal expansion coefficient for gases? Gases are little different than solids and liquids because they neither have definite shape or volume. So we need to be careful while defining its expansion coefficient. In this video, we will explore this in detail :) Created by Mahesh Shenoy. Sort by: Top Voted Questions Tips & Thanks WebFor many solids, expansion is directly proportional to temperature change. ∆ℓ = αℓ0∆T. Areas expand twice as much as lengths do. ∆A = 2αA0∆T. Volumes expand three times as much as lengths do. ∆V = 3αV0∆T. applications. buckling. expansion gap/joint.
