Properties
compressible, expand to fill space, exert pressure, lower density than solids and liquids
Kinetic molecular theory
the smallest entities of a substance are always in motion
Compressibility
distance between particules
Pressure
motion of particules colliding with one another
- amount of force per area
Presure Units
1Pa = 1N/m2
- force per area
Atmospheric pressure
STP: 101.325 = 1atm =760mmHg
SATP: 100 - lab room temp
Law of combining volumes
Gases react in simple who number rations at a constant temp and pressure
Absolute 0
absolute temp scale
-273.15 Celsius =0 kelvin
Celsius to kelvin
add 273.15
Avogandros Theory
Same volume, temp and pressure —. Have the same amount of moles
Molar volume
the amount of volume that a mole of gas occupies - temp and pressure are constant
Boyles Law
pressure and volume are inversely related
Charles Law
Temp and volume a directly related
Gaylussacs Law
tep and pressure are directly related
Molar Volume STP
1 mole of gas occupies 22.4 STP
