Unit 5, Day 2

Agenda

1. Post every group’s graphs — where do they agree, and where not?
2. Linearise the curve: plot volume against $\frac{1}{P}$ and see what happens
3. Name it: The Gas Laws — Boyle, Charles, and the combined form
4. Apply the combined law to your own data and check it against your graph
5. Practise: Gas Law Practice, first set, in pairs

Things to do before our next class

• Gas Law Practice, questions 1–10, with units carried throughout.
• Journal: which of your two graphs you trust more, and why.
