What are the three common states of matter on Earth?
The three common states of matter are solid, liquid, and gas.
How do particles move in a solid?
Particles vibrate in fixed positions and are tightly packed together.
How do particles move in a liquid?
Particles are close together but can slide past one another smoothly.
How do particles move in a gas?
Particles move rapidly, randomly, and are spaced far apart from each other.
Which state of matter has a definite shape and a definite volume?
A solid has both a definite shape and a definite volume.
Which state of matter has a definite volume but takes the shape of its container?
A liquid maintains a fixed volume but adapts to the shape of its container.
Which state of matter expands to fill both the shape and volume of its container?
A gas expands to fill the entire volume and shape of its container.
What is the phase change from a solid to a liquid called?
Melting is the process where a solid turns into a liquid.
What is the phase change from a liquid to a solid called?
Freezing is the process where a liquid turns into a solid.
What is the phase change from a liquid to a gas called?
Vaporization, which includes evaporation and boiling, turns a liquid into a gas.
What is the phase change from a gas to a liquid called?
Condensation is the process where a gas cools and turns into a liquid.
What is sublimation?
Sublimation is the direct transition of a substance from a solid to a gas without becoming a liquid.
What is deposition?
Deposition is the direct transition of a substance from a gas to a solid without becoming a liquid.
What happens to particle motion when thermal energy increases?
Particles gain kinetic energy and move faster as thermal energy increases.
What happens to particle motion when thermal energy decreases?
Particles lose kinetic energy and move more slowly as thermal energy decreases.
What is temperature a measure of?
Temperature measures the average kinetic energy of the particles in a substance.
What happens to a substance's temperature during a phase change?
The temperature stays constant while energy is used to break or form particle bonds.
Which state of matter generally has the strongest attractive forces between particles?
Solids have the strongest intermolecular forces holding particles in place.
What is plasma?
Plasma is an ionized gas consisting of free electrons and positively charged ions.
Why are gases easily compressible compared to liquids and solids?
Gases have large amounts of empty space between their particles.
