AS Level Chemistry - Unit 4.1 The gaseous state: ideal and real gases and pV = nRT

**This Powerpoint specifically uses the Cambridge AS Level Chemistry Syllabus (9701) and covers all criteria for – Unit 4.1 The gaseous state: ideal and real gases and pV = nRT
**

Students will be able to -

1 explain the origin of pressure in a gas in terms of collisions between gas molecules and the wall of the container

2 understand that ideal gases have zero particle volume and no intermolecular forces of attraction

3 state and use the ideal gas equation pV = nRT in calculations, including in the determination of Mr

**Every Powerpoint includes learning objectives, a starter and plenary, suitable activities and review questions with mark scheme. We also provide a free pdf version of the file so it can easily be printed for students as a handout or uploaded to the school VLE system
