The state of a gas is determined by its, 4x
|
volume, temperature, pressure, and composition.
|
|
|
Boyle’s Law
|
Volume is inversely related to pressure
(constant n and T ) P1 V1 = P2 V2 The change in pressure of a gas is indirectly proportional to the change in its volume at a constant temperature, as the pressure increases the volume decreases. |
|
|
Charles’s Law
|
Volume is directly related to the absolute temperature (constant n and P )
v/t = v/t in Kelvin |
|
|
Avogadro’s Law
|
The volume of a gas is directly proportional to the number of gas molecules (constant T and P )
|
|
|
Five liters of a gas exist at a pressure of 700 torr. If the pressure is increased to 1400 torr, the volume of the gas is
|
5L x 700torr = X x 1400torr X = 2.5L
|
|
|
Charles' Law
Note that this relationship is based on temperature in ______ |
Kelvin degrees
|
|
|
O Kelvin =
|
273 + OC
|
|
|
A quantity of gas at 10 deg C and 2 liters volume is heated to 50 deg C. Determine the new volume if the pressure remains constant.
|
X = 2.3 L
|

|
Avogadro's Law: The___________ Relationship
|
Volume-Mole
|
|
|
R =Universal gas constant=.
|
=.08205
|
|
|
P = pressure
SI units |
100kPa = 1 bar 1atm = 101.325 kPa = 760 torr
|
|
|
Dalton’s Law
|
Partial Pressures
The total pressure of a gaseous mixture is the sum of the partial pressures |
|
|
Graham's law states that
|
the rate of effusion of a gas is inversely proportional to the square root of its molecular weight.
