Question

Which of the following properties is different for solids, liquids and gases?

• A. Movement of molecules
• B. Particle size of the substance
• C. Mass of the substance
• D. Energy exchanges between atoms

Answer 1

The correct option is A Movement of molecules

Particles in solids are tightly packed, usually in regular patterns and cannot move from place to place. These are rigid particles locked into one place and are incompressible in nature.

Liquid particles vibrate, move and slide past each other.

Gases vibrate and move freely at high speeds.
