4 h = 760mm Hg for standard atmosphere Vacuum • Pressure: – units of pressure: • mm Hg = Torr • atmosphere (atm) • Pascal (Pa): Pressure – unit factors: 1 atm = 1.01325 x10 5 N/m 2 101.3 Kpa = 1 atm = 760 mm Hg = 760 Torr = 14.7 psi IUPAC units: 1bar = 10 5 Pa Fig. 5.2

5 • Gas Laws: – Boyle (1627-1691): PV = k P = pressure V = volume k = constant at a specific temperature same as the equation describing a straight line: y = mx + b slope intercept Fig. 5.3
