Chapter 8 Flashcards
1
Q
pressure =
A
force / area
2
Q
force =
A
mass x acceleration
3
Q
standard temperature and pressure (STP)
A
The conditions 0 degrees C and 1 atm
4
Q
Partial Pressure
A
that amount of the total pressure which can be attributed to a particular gas
5
Q
Kinetic Molecular Theory of Gases
A
- Molecules separated from each other by distances farg reater than their own dimensions.
* The volume of gas molecules is negligible - Molecules frequently collide with one another, But
* Collisions are perfectly elastic (no energy lost)
* Gas molecules exert neither attractive nor repulsive forces on one another - The average kinetic energy of the molecules is proportional to the temperature of the gas in kelvins.
6
Q
Gas diffusion
A
the gradual mixing of molecules of one gas with molecules of another by virtue of their kinetic properties
7
Q
Gas effusion
A
the process by which gas under pressure escapes from one compartment of a container to another bypassing through a small opening
