100
Tightly packed and vibrates in place
What is a solid
100
A change of state from a solid to a liquid
What is melting
100

The phase change that happens at 0°C

What is melting?

The kinetic molecular theory mainly explains the behavior of this state of matter:

Is it gases

100

This happens to most substances when they are cooled

Do they contract?

200
Particles can slide past each other
What is a liquid
200
Boiling water becomes a
What is gas
200

The phase change that happens at 100°C

What is boiling?

200

This is why gases easily compressed compared to solids

Are gas particles far apart, leaving empty space between them?

200

True or False: Evaporation happens throughout the whole liquid evenly

Is it False?

300
Particles take the shape of the container that it is in
What is liquid
300
The change of a liquid to a gas using heat (no boiling)
What is evaporation
300

The process of liquid water turning into gas.

What is vaporization?

300

The kind of motion do particles in a solid have

Do they vibrate in place due to thermal energy?

300

Ice floats on liquid water because

Is it less dense because ice molecules expand?

400
Fastest moving particles of all the states of matter
What is gas
400
A change from a gas to a liquid
What is condensation
400

The reverse of melting.

What is freezing?

400

This is why gases do not have a definite shape or volume

Are gas particles in constant random motion and spread out?

400

A solid with particles arranged in a repeating 3-D pattern

What is a crystalline solid?

500
When you add energy to a liquid, what happens to the particles?
What is they move faster
500
Changing from a solid directly to a gas
What is sublimation
500

The reverse of vaporization.

What is condensation?

500

According to kinetic theory, what are the three types of particles that can make up matter

Is it atoms, molecules, and ions?

500

A solid with particles placed randomly.

What is an amorphous solid?
