Particle Theory rules
Real life examples
Heating/Cooling
100

This state of matter has particles packed tightly together that only vibrate in place.

What is a solid?

100

This rule states that all matter is made up of tiny particles.

What is the first principle of particle theory?

100

The smell of perfume spreading across a room is an example of this particle process.

What is diffusion?

100

When matter is heated, particles begin to move this way.

What is faster?

200

In this state of matter, particles can slide past each other but stay close together.

What is a liquid?

200

Particles are always doing this, even in solids.

What is moving?

200

When ice cubes melt in a drink, the solid water changes into this state.

What is a liquid?

200

When matter cools, particles move this way.

What is slower?

300

This change of state happens when a gas turns back into a liquid.

What is condensation?

300

When the temperature increases, particles do this.

What is move faster?

300

When a puddle disappears on a warm day, this change of state occurs.

What is evaporation?

300

Heating a solid until it turns into a liquid is called this.

What is melting?

400

This change of state happens when a solid turns into a gas.

What is sublimation?

400

Particles attract each other with these invisible forces.

What is force of attraction?

400

When you spray air freshener and the scent spreads through the room, particles are doing this.

What is spreading out and moving freely?

400

Cooling a liquid until it becomes a solid is called this.

What is freezing?

500

This change of state happens when a gas turns into a solid.

What is deposition?

500

There are spaces between these in all matter.

What are particles?

500

When moist air turns into frost on a cold morning.

What is deposition?

500

When a liquid is heated, its particles move faster and spread farther apart. This often causes the liquid to take up more space. What is this process called?

What is thermal expansion?
