List the 3 common states of matter
Solid, Liquid and Gas

Okay!
Describe what happens to the particles in a liquid when it is heated?
The particles get more energy and move faster and faster, eventually breaking away from the liquid state and forming a gas
Oops!
Okay!
Explain condensation
Is the changing of a gas to a liquid - when a gas is cooled the particles slow down and liquid is formed.
