Explains properties of matter in terms of the _____ of the particles and the _____ that act between them

3. Kinetic-Molecular Theory of Gases
The theory provides a ______for an ideal gas.
______________: a hypothetical gas that ____________all the assumptions of the ________________________
__________: a gas that does ____behave completely according to the assumptions of the kinetic-molecular theory

4. Five Assumptions
Gases consist of large numbers of tiny _________that are _______relative to their ________
__________between gas particles and between particles and container walls are _________collisions
____________: one in which there is no _________________________(energy is not transferred between the particles)

5. Assumptions
Gas particles are in __________, ____, ______motion. They therefore possess _________energy
There are no __________________ between gas particles
The ____________of a gas depends on the average _________________of the particles of the gas

6. Physical Properties ______________
Gas particles move rapidly in all ___________with no ____________
This explains why gases do not have a ______________________
They completely fill the ___________and take its _____________

7. Fluidity
The ability of particles of a substance to _________past one another.

Gases spread out without being stirred or ____________.
The gas particles will naturally move throughout the available ____________.

10. Effusion
_____________: a process by which gas particles pass through a ____________
An example of this would be the air coming out of a leak in a car tire.
Molecules of ______mass effuse _____ than molecules of _________mass (the “lighter” molecules move faster)

11. Deviations of Real Gases from Ideal Behavior
All real gases deviate from ideal behavior to some extent.
At very __________________and ____ ________________, when compared to “normal” conditions, real gases are ____ likely to behave _________.
