Interpret pressure, volume, and temperature data

Paper 1, Paper 2 5 marks Difficulty 4

Temperature from volume trend

At constant pressure in a entropy mixing demonstration, gas volume changes from \(2.2\,\text{L}\) at \(290\,\text{K}\) to \(2.8\,\text{L}\). Calculate the final temperature. 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.
