Notes - All values refer to 25 °C and to the thermodynamically stable standard state at that temperature unless noted.
- Values from CRC refer to "100 kPa (1 bar or 0.987 standard atmospheres)". Lange indirectly defines the values to be at a standard state pressure of "1 atm (101325 Pa)", although citing the same NBS and JANAF sources among others. It is assumed this inexactly refers to "ambient pressure".
The Celsius scale is a temperature scale named after the Swedish astronomer Anders Celsius (1701 â 1744), who first proposed a similar system two years before his death. ...
The pascal (symbol Pa) is the SI unit of pressure. ...
Atmospheric pressure is the pressure caused by the weight of air above any area in the Earths atmosphere. ...
