Particle Theory of Matter
According to the Particle Theory of Matter, all matter is made up of these.
What are particles?
The three common states of matter.
What are solid, liquid, and gas?
The change from a solid to a liquid.
What is melting?
A mixture in which the components are uniformly distributed (you can't see the different parts).
What is a homogenous mixture?
This is the amount of space an object takes up.
What is volume?
Particles of matter are always doing this.
What is moving?
The state of matter where particles are spread far apart and move quickly.
What is gas?
The change from a liquid to a gas.
What is evaporation (boiling)?
A mixture where the different parts can be seen and separated easily.
What is a heterogenous mixture?
This term describes anything that has mass and takes up space.
What is matter?
Particles move faster when the temperature does this.
What is increases?
A state of matter that has a fixed volume but no fixed shape.
What is liquid?
The change from a gas to a liquid.
What is condensation?
The component of a solution that dissolves the solute.
What is the solvent?
This is the amount of matter in an object.
What is mass?
In solids, particles are arranged in this way.
What is tightly packed?
This state of matter has a definite shape and volume.
What is a solid?
The change from a liquid to a solid.
What is freezing?
A substance dissolved in a solvent to form a solution.
What is a solute?
A substance that cannot be separated into simpler substances by physical means.
What is a pure substance?
The theory that explains the behavior and movement of particles in matter.
What is the Particle Theory of Matter?
What states of matter does Oobleck (cornstarch and water) act like?
What is a liquid and solid?
The process where a solid changes directly into a gas without becoming a liquid first.
What is sublimation?
A mixture of substances that looks the same throughout but can still be separated physically.
What is a solution?
These types of mixtures, such as pesticides and fertilizers, can be dangerous if not handled correctly.
What are dangerous mixtures?
