Boyle relationship pressure

A gas in a greenhouse model investigation changes volume from \(2.6\,\text{L}\) to \(1.8\,\text{L}\) at constant temperature. Initial pressure is \(115\,\text{kPa}\). Calculate the final pressure. Enter the numerical result and choose the interpretation that matches the physical meaning.

Worked practice: physics data and result

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