It is mean atmospheric pressure at sea level.
Standard pressure is defined as 1atm, or 760mmHg. This is sea-level atmospheric pressure here on earth.
Standard pressure is 760mm Hg, so the difference in pressure is 40mm Hg (760mm - 720mm).
The pressure at standard temperature and pressure (STP) is 1 bar.
The SI unit for pressure is a Pascal but in this case the standard unit is the standard atmosphere (= 101325 Pa).
Standard temperature and pressure (STP) is a standard by which comparisons can be made. STP is 0°C (273 K) and 1.00 ATM (760 mmHg, 101.325 kPa). Molar volume is based upon the conditions at STP, which is 22.4 L for 1 mole of any [ideal] gas.
Gold is a liquid at 758K and standard pressure.
Standard pressure is defined as 1atm, or 760mmHg. This is sea-level atmospheric pressure here on earth.
1 atm (standard atmospheric pressure) is 101,325 kPa.
One standard atmosphere of pressure is equivalent to 101.325 kilopascals.
1 atm (standard atmospheric pressure) is 101,325 kPa.
The standard value for air pressure at sea level is around 1013.25 millibars, or 29.92 inches of mercury (inHg).
For chemistry, after IUPAC rules the standard temperature is 0 oC and the standard pressure is1 bar.
Standard pressure is 760mm Hg, so the difference in pressure is 40mm Hg (760mm - 720mm).
Standard temperature and pressure (STP) is defined as a temperature of 0 degrees Celsius and a pressure of 1 atmosphere (atm).
One standard atmosphere of pressure is approximately equal to 101.3 kilopascals.
The saturation temperature of water at standard atmospheric pressure is 100 degrees Celsius.
The standard unit of measurement for pressure in fluid dynamics is the Pascal (Pa).
