• solid, liquid, plasma

• solid, element, matter

• fluid

• brittle

• malleable

• ductile

Has a fixed volume, definite shape, and does not flow

• solid

• liquid

• gas

• plasma

Has a fixed volume, no definite shape but takes the shape of the container and generally flows easily

• solid

• liquid

• gas

• plasma

no fixed volume, no definite shape and flows easily

• solid

• liquid

• gas

• plasma

the temperature at which a solid turns into a liquid.

• melting point

• boiling point

• freezing point

• focal point

At higher temperatures

• 
  particles in an object have less energy

• 
  a gas contracts

• particles in an object move faster

Freezing is the process of

• Solid to gas

• gas to solid

• liquid to solid

• solid to liquid

Boiling is the process of

• liquid to gas

• gas to liquid

• solid to gas

• solid to liquid
