Which of the following is most elastic ?
Correct answer: A. Steel
- A. Steel
- B. Rubber
- C. Glass
- D. Sponge
- E. None of these
Explanation
Elasticity means the ability to regain the original shape after deformation, and steel has a higher elastic modulus than rubber, glass or sponge. Rubber stretches more, but greater stretch does not mean greater elasticity in this scientific comparison.
