This state of matter has particles packed tightly together that only vibrate in place.
What is a solid?
This rule states that all matter is made up of tiny particles.
What is the first principle of particle theory?
The smell of perfume spreading across a room is an example of this particle process.
What is diffusion?
When matter is heated, particles begin to move this way.
What is faster?
In this state of matter, particles can slide past each other but stay close together.
What is a liquid?
Particles are always doing this, even in solids.
What is moving?
When ice cubes melt in a drink, the solid water changes into this state.
What is a liquid?
When matter cools, particles move this way.
What is slower?
This change of state happens when a gas turns back into a liquid.
What is condensation?
When the temperature increases, particles do this.
What is move faster?
When a puddle disappears on a warm day, this change of state occurs.
What is evaporation?
Heating a solid until it turns into a liquid is called this.
What is melting?
This change of state happens when a solid turns into a gas.
What is sublimation?
Particles attract each other with these invisible forces.
What is force of attraction?
When you spray air freshener and the scent spreads through the room, particles are doing this.
What is spreading out and moving freely?
Cooling a liquid until it becomes a solid is called this.
What is freezing?
This change of state happens when a gas turns into a solid.
What is deposition?
There are spaces between these in all matter.
What are particles?
When moist air turns into frost on a cold morning.
What is deposition?
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?
