This has no definite shape, but does have a definite volume
What is a Liquid?
A change in matter that involves a change in a physical property but doesn't create a new substance
What is Physical change?
H20 (water) and CO2 (carbon dioxide) are examples of this as they are made up of different elements bonded together.
