Question

Matter with no fixed shape but definite volume exist in following state.

• A. Solid
• B. Liquid
• C. Gas
• D. gaseous

Answer 1

The correct option is B

Liquid

Explanation for correct option

(B) - Liquid

Liquid state -

• Particles are loosely packed.
• The interparticle force of attraction is lesser than the solids and so the particles are present at some distance from each other.
• The inter-particle space is more, and so the particle move freely around other particles.
• Kinetic energy of the particles is more than the solids.
• Liquids have a definite volume but no definite shape.

Explanation for incorrect options

(A) - Solid

• The particles are tightly packed.
• The interparticle force of attraction is very strong.
• The interparticle space is almost negligible and so the movement of particles is very limited and they move about their fixed position only.
• Kinetic energy of the particles is very low.
• Solids have a fixed shape and definite volume.

(C) - Gas, (D) - Gaseous

• In gaseous state, the particle is present far apart from each other.
• The inter-particle force of attraction is negligible as compared to solids and liquids. Hence the particle moves around freely and independently.
• The interparticle space is very large and so the gases occupy the entire space available in a container and do not have a definite volume and can be compressed easily.
• Kinetic energy of the particle is very high. The particles move around freely colliding with each other and also with the walls of the container.
• Gases have no fixed shape and no fixed volume.

Hence option (B) is the correct answer.
