STP - Standard Temperature and Pressure - is defined by IUPAC (International Union of Pure and Applied Chemistry) as air at 0 o C (273.15 K, 32 o F) and 10 5 pascals (1 bar). STP - …

Standard temperature and pressure (STP) means a temperature of 273.15 K (0 °C or 32 °F) and a pressure of 1 atm (101.35 kPa). In practice, this corresponds to the freezing point of pure …

The International Union of Pure and Applied Chemistry (IUPAC) defines standard temperature and pressure as follows: A temperature of 0 0 C or 273.15 K A pressure of 10 5 Pa or 1 bar …

The conditions at STP are: Temperature: 273.15 K (0°C or 32°F) Pressure: 10 5 Pascals (formerly 1 atm, but IUPAC has since changed this standard). Since the volume of a gas depends on …

NIST uses a temperature of 20 °C (293.15 K, 68 °F) and an absolute pressure of 1 atm (14.696 psi, 101.325 kPa). This standard is also called normal temperature and pressure (abbreviated …
