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.
