This is a lesson and PowerPoint introducing the Pressure Law (Temperature vs Pressure at constant Volume). This is the seventh lesson in the Particle Model unit of work (P3). The lesson covers the qualitative analysis of pressure changes due to temperature changes at constant volume using the particle theory of matter. Extension ideas are included for a quantitative analysis from a graph. The lesson plan is step by step including extension ideas and the learning objectives linked directly to the syllabus.

This is a brief lesson and PowerPoint explaining the heating and cooling effect of changing the pressure f a gas in a fixed volume. This is the tenth lesson in the Particle Model unit of work (P3). The lesson covers the heating and cooling of gases, work done calculation and links to two external youtube clips showing these effects. The lesson plan is step by step including extension ideas and the learning objectives linked directly to the syllabus.
