what is a liquid?
a substance that flows freely but is of constant volume
a substance or matter in a state in which it will expand freely
firm and stable in shape
what is a gas?
a substance or matter in a state in which it will expand freely to fill the whole of a container
the basic unit of a chemical element
an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
How would you describe the way molecules move when the molecules are solid?
the molecules are moving in place.
the molecules are moving around each other.
the molecules are moving away from each other.

Molecules are always moving no matter what phase they are in: solid, liquid, gas.
True
False
What happens to molecules when the temperature drops or lowers?
