Ch. 14 Review – Gases
Kinetic-Molecular theory
(These assumptions relate to “ideal gases”)
1. Gas particles do not attract or repel each other
2. Gas particles have no volume
3. Gas particles are in constant, random motion
4. No kinetic energy is lost when gas particles collide with each other or
the walls of their container
5. all gases have the same kinetic energy at a given temp.
Real Gases – 1) do have volume
2) do exert attractive forces on each other
Real gases behave like ideal gases when??
**very low pressure (molecules far apart)
**very high temperature (moving too fast to exert attractive forces)
Nature of gases
conditions
They are fluid
They are able to diffuse
They have a low density
They can be compressed
They can expand
Boyle’s Law
At a constant temperature – the volume of a gas varies
P1V1 = P2V2
P1 T1 V1 – initial
(original, starting)
P2 T2 V2 – final conditions
(new, end)
indirectly with the pressure
Pressure conversions
1 atm = 760 mmHg = 760 torr = 101.3 kPa
Charles’s Law
At a constant pressure – the volume of a given mass of gas is directly related to its Kelvin temp.
V1 = V 2
T1 T2
K = oC + 273
Gay- Lussac’s Law
At a constant volume – the pressure of a given amt of gas varies directly with the Kelvin temp.
P1 = P2
T1 T2
Combined Gas Law
Volume/pressure/temp – are all related to each other as in the other gas laws (Pressure is inversely
related to volume and directly related to temp and volume is directly related to temp)
P1V1 = P2V2
T1
T2
Ideal Gas Law
You are adding the number of particles to the equation (n) as moles. The # of particles will affect at
least one of the other three variables
(increasing the # of part. will raise the pressure if the V & T are kept constant – if P & T are kept
constant, adding part. will increase V)
PV = nRT
3 ideal gas constants (“R” value)
Atm = .0821
mmHg – 62.4
kPa – 8.314
