Characteristics of gases
|
assume volume and shape of container
most compressible state of matter unreactive gases will mix evenly and completely when confined to the same container lower density that liquids and solids |
|
|
Pressure
|
the force applied per unit area of surface
|
|
|
P=
|
force / area
|
|
|
P units
|
kG/ms^2 =pascal (Pa)
Pascal is SI unit for pressure |
|
|
1Pa=
|
1N/m^2
|
|
|
I bar=
|
10^5 pa
|
|
|
1 atm=
|
760 mmHg
760 torr 101,325 Pa |
|
|
1 torr=
|
1mmHg
|
|
|
Boyle's law
|
inverse relation between pressure and volume
V=C x 1/P PV=C=PV |
|
|
Charles Law
|
V= C x T
V/T =V/T |
|
|
Combined Gas law
|
PV/T=PV/T
|
|
|
Avogadro's law
|
molar gas volume
V=C x n V/n =V/n V=RnT/P |
|
|
Ideal gas law
|
PV=nRT
|
|
|
ideal gas
|
hypothetical gas with behavior that can be accounted for by the ideal gas equation PV=nRT
ideal gases don not exist - the molecules do not attract or repel one another - the volume of the molecules is negligible compound with the volume of the container |
|
|
real gases
|
do exist
behave ideally in certain cercumstances |
