Chemistry Gas Laws gasesoutlinerev2.doc Quantities under discussion: Pressure (P), Volume (V), number of moles (n), Temperature (T, in kelvin) Pressure is: Force per unit area P = F/A in SI units pressure is in Pascals (Pa) 1 Pascal = 1 N/m 2 Other units of pressure: Atmosphere (atm) : Equal to the average pressure of the atmosphere at sea-level on the Earth Kilopascals (kPa) : 1,000 pascals Torricelli (torr or mmHg) : Equal to the pressure at the bottom of a column of Mercury that is measured in millimeters. Named after Evangelista Torricelli, a scientist who worked with gases. Inches of Mercury (inHg) : Meteorological measurement which gives pressure relative to the pressure provided by a column of mercury measured in inches. Pounds per Square Inch (psi) : Equal to the force in pounds per square inch of surface area. This unit is not commonly used in science. Unit relationships: 1 atm = 760 torr = 101,300Pa = 101.3kPa = 29.92 inHg = 14.70 psi Measuring the pressure of gases : A manometer
