Question

what happened to the modulus of elasticity of most of the material with increase in temperature​

Answer 1

When the temperature increases, the atomic thermal vibrations increase, and this will cause the changes of lattice potential energy and curvature of the potential energy curve, so the Young's modulus will also change. And with the increase of temperature, the material will have a volume expansion.

Answer 2

Answer:

there will be no change

it will remain the same as temperature is inversely proportional to elasticity
