On increasing temperature, the elasticity of a material

On mixing impurities, the elasticity of a material

On mixing impurities, the elasticity of a material

(A) : With increase in temperature, elastic property of a substance decreases (R): Elasticity is due to intermolecular forces which decrease with increase of intermolecular distance

Statement 1: On increase in temperature ferromagnetic material converts into paramagnetic material. Statement 2: At high temperature, randomness of domains ferromagnetic material increases

Assertion: With increase of temperature, elastic property of a substance decreases. Reason: Elasticity is due to intermolecular forces which decreases with the increase of intermolecular distance.

On what factors does the elasticity of a material depend ?

For which material with increase in temperature resistivity decrease ?
