Stuff
& Substance aims to establish the chemical idea
of a substance. The phenomena of the material world can be
understood in terms of three different things that could happen
to a sample of a substance:
 |
It could change
state;
|
|
It could mix up with one or
more other substances;
|
|
It could undergo chemical change
on its own or in interaction with another substance.
|
These three possibilities give rise to the three sections
of Stuff & Substance:
|
Substances
|
|
Mixtures of Substances
|
|
Changing Substances |
