Young s modulus is a numerical constant named by English physicist Thomas Young in 1807. The property of elasticity is the result of interatomic attraction found in any material at microscopic levels. Naturally it will be the greatest in the case of solids and the least in the case of gas. The elasticity of gas is almost negligible.
