Volume: is how much space an object takes up.
~ It will always be the same.
Liquids: A type of Matter that Volume will stay the same. The shape may change.
Ex: The same amount of water may change shape in two different cups. If one is long and skinny then the water will be long and skinny. As opposed if it is short and fat then its shape will be short and fat. (FYI Might want to take 2 glasses and pour water in it.)
Gas: There is no definite shape or definite volume.
