States of matter (CP_

At higher temperatures

• particles in an object have less energy
• particles in an object move faster
• a gas contracts

A gas

• has a definite shape but no definite volume
• has a definite volume but no definite shape
• has fast-moving particles

The state of matter that has no definite size or shape is

• Solid

• Liquid

• Gas

Particles of a liquid

• are tightly packed together and stay in a fixed position.

• are free to move around one another but still touch.

What is condensation?

• gas to solid

• gas to liquid

• liquid to solid

What is increasing as time increases?

• state of matter
• boiling point
• melting point
• kinetic energy

Evaporation is when liquid particles absorb enough energy to leave the 

• surface
• bottom
• center
• liquid throughout

Sublimation is

• when solid turns into gas
• when gas turns into plasma
• when liquid turns into gas
• when gas turns into solid

Fluid states are

• solid and gas
• liquid and gas
• solid and liquid
• solid, liquid and gas

If a solid does not have a uniform crystalline structure, it is considered

• an allotrope
• a liquid
• amorphous
• a metal
