Most students memorise PV formulas.
Confident students see the connections.
In this recap, Mr. Terence go through the key formulae and shortcuts for solving PV graphs — not just what to use, but why it works.
If you're taking H2 Physics, your improvement doesn’t come from memorising more equations. It comes from understanding how:
•
PV=nRT
PV=nRT links to gas processes
• The First Law connects energy and work
• Isothermal, isobaric and isochoric processes change the graph behaviour
• Internal energy ties everything together
This video helps you refresh your foundation and see the logic that connects the concepts.
