Particle Motion | MCQs

Explanation

• In a solid, the particles are closely packed and have a fixed position.
• But they still have some freedom to vibrate or oscillate in place, due to their thermal energy.

Explanation

In a gas, the particles are:

• Widely spread out, with no fixed position or arrangement
• Not in a regular pattern, with no repeating structure or order
• Separated by large empty spaces, with no close packing or cohesion

Explanation

The particles in a gas have the following characteristics:

• They move randomly, with no fixed pattern or direction
• They have unlimited space to move, as there are no boundaries or restrictions
• They move freely in any direction, without any obstacles or barriers
• They can travel long distances, as there are no constraints on their movement

Explanation

• The correct answer is: Particles have large empty spaces between them.
• This statement is incorrect because particles in liquids have small spaces between them, not large empty spaces.

Explanation

• The incorrect statement is: Particles are in loose clusters.
• In solids, particles are actually closely packed and arranged in a regular pattern, with minimal space between them.
• This is what gives solids their rigidity and structure.
