standard atmospheric pressure
1Atmospheric pressure — Air pressure redirects here. For the pressure of air in other systems, see pressure. Atmospheric pressure is the force per unit area exerted against a surface by the weight of air above that surface in the Earth s atmosphere. In most… …
2atmospheric pressure — n. the pressure due to the weight of the earth s atmosphere, usually measured by a standard unit: see ATMOSPHERE (sense 7) …
3Atmospheric Pressure Chemical Ionization — (chemische Ionisation bei Atmosphärendruck, APCI) ist ein Ionisierungsverfahren, das in Massenspektrometern verwendet wird. Es ist eine Form der chemischen Ionisierung bei atmosphärischen Druck. Eine Lösung des Analyten wird durch eine Kapillare… …
4atmospheric pressure — Meteorol. 1. the pressure exerted by the earth s atmosphere at any given point, being the product of the mass of the atmospheric column of the unit area above the given point and of the gravitational acceleration at the given point. 2. a value of …

7standard atmospheric conditions/standard atmosphere — The internationally accepted conditions of the atmosphere to allow all measurements to be brought to the same norms. The standard atmospheric conditions at sea level are pressure: 29.92 in of mercury or 1013.2 hectopascals; temperature: 15°C;… …
8Atmospheric Pressure — The pressure of the air at sea level; one standard atmosphere at zero degrees centigrade is equal to 14.695 pounds per square inch (1.033 kilograms per square centimeter) …
9Standard atmosphere — can refer to:* A standard reference value for air pressure: ** Atmosphere (unit), an approximation of the value at sea level ** Atmospheric pressure, other reference values * A model of how atmospheric pressure varies with altitude: ** The U.S.… …
10Pressure cooking — is a method of cooking in a sealed vessel that does not permit air or liquids to escape below a preset pressure. Because the boiling point of water increases as the pressure increases, the pressure built up inside the cooker allows the liquid in… …
