100

In this state of matter, the particles are relatively far apart from each other, compared to a liquid or a solid.

State of gas

100

An increase in the temperature of a contained liquid that increases 

What is Vapor pressure?

100

This is the transition from a solid to a liquid

Melting?

100

This is the transition from vapor to a solid

Deposition
200

The smallest group of particles within a crystal that retains the geometric shape of the crystal

Unit cell
200
This is the force exerted by a gas
Gas pressure
200

This is why gases are hard to contain outside a closed container

Lack of molecular attraction

200
Absorbed energy speeds up
Particles

What determines the shape of a crystal?
Arrangement of the particles within the solid
300
Energy that an object has because of its motion
Kinetic energy
300
Empty space with no particles
Vacuum
300

This happens when a closed system reaches the same rate of evaporation and condensation

Equilibruim

300

Device that is used to measure atmospheric pressure

Barometer
300
The temperature of a boiling liquid never rises above its
Boiling point
400
Theory explaining the states of matter based on the concept that all matter consists of tiny particles that are in constant motion.
Kinetic theory
400

This scale reflects the relationship between temperature and average kinetic energy.

Kelvin temperature

400

This is what gives liquids its properties

Interaction between molecules
400

This is a group of solids that have higher melting points because of stronger bonds

Ionic solids

400
Temperature at which a liquid changes into a solid
Freezing point
500

Describes the only set of conditions at which all three phases can exist in equilibrium with one another

Triple point

Increase in energy results in
Increase in temperature
500
The vapor pressure of a liquid can be determined using a 
Manometer
500
Atmospheric pressure depends on
Weather and altitude

Why do allotropes contain different properties?
They have different structures
