Ideal gas pressure
A gas in a refrigeration cycle model has \(0.15\,\text{mol}\), volume \(0.003\,\text{m}^{3}\), and temperature \(300\,\text{K}\). Use \(R=8.31\). Calculate pressure in kPa. 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.
