Pressure temperature relationship

A fixed-volume gas in a marine science sensor test has pressure \(150\,\text{kPa}\) at \(305\,\text{K}\). Its temperature becomes \(355\,\text{K}\). 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.
