4.1 Empirical Properties of Gases

all the way to slide 9 - set 1 of PowerPoint 1 - definitions and units to remember for calcs.

atmospheric pressure

force per unit area exerted by air on all objects

atmospheric pressure standard sea level pressure

101.325 kPA

tell me the value for the main calculations

760 mmHg = 1atm = 101.325kPa

standard temp and pressure

1 atm at 0 degrees Celsius AND 101.325k kPa at 273.15K

Standard Ambient Temperature and Pressure

100kPa at 25 degrees Celsius (room temp.) AND 100kPa at 298.15K

which is more preferred and wny, STP OR SATP

SATP because it is at room temp so more convenient

1 N/m2 = ????

1 Pa

absolute zero

lowest temp which all molecular motion stops
