Standard 5d Preknowledge
5d) Students know the values and meanings of standard temperature and pressure (STP).
CALIFORNIA FRAMEWORKS SUMMARY: Standard temperature is 0°C, and standard pressure (STP) is 1 atmosphere (760 mm Hg). These standards are an agreed-on set of conditions for gases against which to consider other temperatures and pressures. When volumes of gases are being compared, the temperature and pressure must be specified. For a fixed mass of gas at a specified temperature and pressure, the volume is also fixed.
