What Chemistry Studies
Captions available
The idea
Chemistry is the study of matter — anything that occupies space and has mass — and the changes matter undergoes.
In practice
Ice melting into liquid water is a change chemistry studies: the same substance, a different physical state.
Where people slip
Students often picture chemistry as only dramatic lab reactions; the field equally covers ordinary changes like rusting, cooking, and dissolving.
