(P,V) are inversely related.
(P,T) and (V,T) are directly related.

Avogadro’s Principle (1811) An observation that is an
extension of KMT All gases are assumed to have
the same particle size. Equal volume of 2 gases will
have the same # of particles!

For any gas:
6.02 x 1023 particles = 22.4 L

Topic: Ideal Gas Law Date: 5/13/2013
Practice Problem:A 2.0L sample of gas has a
pressure of 1.5atm. If 5.0 moles occupy the sample, what is the temperature?
Example
PV = nRT(1.5)(2.0) = (5.0)
(0.0821)x3 = (0.4105)x
0.4105 0.4105
x = 3/0.4105x = 7.308K = T
P = 1.5atmV = 2.0Ln = 5.0molR = 0.0821 L·atm/mol·KT = x
Reflection
In your notes answer the following question:
How can you predict how a gas will be affected in a given situation? (in terms of P, V, n, and T)
