Answer 1

Explanation:

1. The elasticity of a substance is affected by Impurity of substance, Hammering and annealing, Change in temperature.

2. Sry l don't

3. There are various elastic moduli, such as Young's modulus, the shear modulus, and the bulk modulus, all of which are measures of the inherent elastic properties of a material as a resistance to deformation under an applied load. The various moduli apply to different kinds of deformation.

4. The correct increasing order of cottidest eten of Coppe St. Class and Rubber is. (1) Steel Rubber Copper C.
