Frequently asked questions
- What is standard temperature and pressure (STP)?
- STP is 273.15 K (0 °C) and 101,325 Pa (1 atm). One mole of ideal gas occupies 22.414 litres at STP.
- When does the ideal gas law break down?
- At very high pressures or very low temperatures, intermolecular forces matter and you need the van der Waals equation or other corrections.
