Apply ideal gas relationships

Paper 1, Paper 2 5 marks Difficulty 3

Boyle law pressure

A gas in a refrigeration cycle model changes volume from \(2.2\,\text{L}\) to \(1.3\,\text{L}\) at constant temperature. Initial pressure is \(125\,\text{kPa}\). Calculate the final pressure. Use the diagram first, then calculate the requested value. Enter the numerical result and choose the interpretation that matches the physics meaning.

Worked practice: physics data and result

Read the physical quantities first, then calculate the result and state what it means.
