Learning Objective
I can apply the law of conservation of mass to chemical reactions.

The law of conservation of matter states that matter cannot be created or destroyed, only converted from one form to another.
- 2
When water boils, the steam has the same mass as the liquid water because the water molecules only speed up and move away from each other.
- 3
When a copper pipe rusts, it gains mass because oxygen atoms from the atmosphere bond to the copper atoms in the pipe.
