Correct Answer: C. Ratio of stress to strain is more

Detail about MCQs

Steel is more elastic than rubber because:
C. Ratio of stress to strain is more
Elasticity is characterized by the ratio of stress to strain, known as the Young’s modulus. Steel, being a material with a high Young’s modulus, has a higher ratio of stress to strain compared to rubber, which means it is more elastic. Rubber has a lower Young’s modulus and thus is less elastic.

Between the melting point and boiling point of a substance, the substance is a?

A. Solid
B. Liquid
C. Gas
D. Crystal

Answer

Correct Answer: B. Liquid

Detail about MCQs

A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a nearly constant volume independent of pressure. It is one of the four fundamental states of matter, and is the only state with a definite volume but no fixed shape.
