Question

Particle of matter in gaseous state have more kinetic energy than in solids.

• A. True
• B. False

Answer 1

The correct option is A True

Definition of matter

Matter is made up of very small particles called atoms. Atoms are the building blocks of matter.

According to kinetic theory of matter, all matter exist in three states-solid, liquid and gas

Solid state-

• 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.

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.

Gaseous state -

• In gaseous state, the particles are 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.

Hence the given statement is true. ie., particles of matter in the gaseous state have more kinetic energy than solids
