4.3.3.2 Pressure in gases

Spec reference: 4.3.3.2 (physics only).

Triple-only content in this dot

• Use particle model to explain pressure-volume changes at constant temperature.
• For fixed mass of gas at constant temperature: pV = constant.

Exam quick-check

• Can I identify this as a triple-only point from wording in the question?
• Can I apply the correct equation/idea with units and a clear conclusion?
