another process where a liquid becomes a gas
Properties are used to identify substances
Substances have characteristic properties
Properties of a substance to identify it
Identifying substances
Density can be used to identify substances
Finding any matching densities will give you info on identy
Separation
Magnetic properties
If you have aluminum and steel cans you can use a magnet to separate the cans
To differentiate two or more objects
