If Young's modulus for a material is zero, then the state of material should be
Correct answer: C. Gas
- A. Solid
- B. Solid but powder
- C. Gas
- D. None of the above
Explanation
Young's modulus measures a material's stiffness, or its ability to resist deformation. A material with a zero Young's modulus does not resist deformation at all, which is characteristic of gases. Solids and powders, even though they can be broken down into smaller particles, still possess some resistance to deformation, which means they cannot have a zero Young's modulus. Therefore, the correct answer is 'Gas', as gases can easily change shape and volume without resistance.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
