Document Summary
Si base units = n/m^2 = pa (pascal) torr atm bar kpa conversions to know. 1. 00 atm = 760 mm hg = 760 torr = 1. 013 bar = 101. 325 kpa = 14. 7 psi measuring atmospheric pressure barometer = instrument used for measuring atmospheric pressure. P(column) = p(atm) atmosphere exerts a pressure equal to pressure exerted by a column of mercury 760 mm tall. 1 atm = 760 mmhg measuring gas pressure in laboratory manometer = u-shaped tube containing mercury for measuring gas pressure pressure of gas sample balanced by pressure of atmosphere and pressure of mercury column scenarios possible. P(atm) < p(gas) and p(gas) = p(atm) + p(column) gases2. P(atm) > p(gas) and p(atm) = p(gas) + p(column) what are 4 basic gas properties " all interrelated = changing one property affects others pressure (p) units gases3 atm, torr, mmhg volume (v) L or ml amount (n) moles molecules mass temperature.
