1. Equation of state and ideal gases

2. Gases assume the volume and shape of their containers.
Gases are the most compressible state of matter.
Gases will mix evenly and completely when confined to the same container.
Gases have much lower densities than liquids and solids.

3. An “ideal” gas exhibits certain theoretical properties
An “ideal” gas exhibits certain theoretical properties. Specifically, an ideal gas …
Obeys all of the gas laws under all conditions.
Does not condense into a liquid when cooled.
Shows perfectly straight lines when its V and T & P and T relationships are plotted on a graph.

4. Ideal Gas Equation
Boyle’s law: V 1/P (at constant n and T)
Charles’ law: V T (at constant n and P)
Avogadro’s law: V n (at constant P and T) V
V=constant x =R R is the gas constant
PV = nRT n, V and R are constant

5. Where S is a entrophy
T is a temperature
V is a volume
P is a pressure
This is known as first TDS equation
