How does a physical change differ from a chemical change?

• In a physical change new volumes are created.

• In a physical change new materials are produced.

• In a physical change the substance is unchanged.

• In a physical change the change is not reversible.

What is the law of conservation of mass?

• Chemical changes result in the formation of new substances and loss of mass.

• Matter cannot be created or destroyed; it will only change forms.

• Chemical changes result in the formation of new substances and loss of volume.

• Matter can only be changed from one state to another; never forming new substances.
