States of Matter and Particle Motion in Everyday Life

The video tutorial explains the states of matter—solid, liquid, and gas—and how particle motion affects their state changes. It covers how increasing or decreasing particle motion through heat energy can change a substance's state. The tutorial details six state changes: melting, vaporization, sublimation, condensation, freezing, and deposition, with examples from daily life to illustrate these concepts.

What is the primary motion of particles in a solid?

• They move freely in all directions.

• They vibrate about their mean position.

• They move in a circular path.

• They remain completely still.

How do liquid molecules move?

• They move in a fixed path.

• They move randomly in all directions.

• They remain stationary.

• They vibrate in place.

What happens to a solid when the motion of its particles is increased?

• It becomes a gas.

• It becomes a plasma.

• It remains a solid.

• It changes to a liquid.

• Freezing

• Sublimation

• Condensation

• Vaporization
