Everything you need to know about polymers!<b<br/>r/>

Polymers are large molecules made up of lots of repeating units called monomers. This video covers: how to identify them, how to draw them, and their properties.

This video explains 'particle theory' and uses it to describe the 3 states of matter: solid, liquid and gas. It also covers how substances move between these states at the particle level. This video is suitable for: - All exam boards -...

In this video, you'll learn:

- What the term 'purity'
means
- How we use physical and chemical tests to check
for purity
- The effect of purity on melting and
boiling points
- What the term
'formulation' means
