KINETIC
MOLECULAR (K-M) THEORY OF MATTER (p. 385 – 387 & p. 419 – 420 in text book)
- based on the idea that particles of mattter are always in motion
- assumptions of the K-M Theory
1.) Gases consist of large numbers of
tiny particles that are far apart relative to their size.
This
means that _________________________________________________________
______________________________________________________________________
2.) Collisions between gas particles and between
particles and container walls are elastic
collisions. This means that
________________________________________________
______________________________________________________________________
______________________________________________________________________
3.) Gas particles are in constant,
rapid, random motion.
This
can be inferred because ______________________________________________
4.) There are no forces of attraction
or repulsion between gas particles.
This
means that _________________________________________________________
_______________________________________________________________________
_______________________________________________________________________
5.) The average kinetic energy of gas
particles depends on the temperature of the gas.
This
means that _________________________________________________________

- GASES BEHAVE NEARLY
IDEALLY UNDER CONDITIONS of _________ temperature,
_________ pressure, &
_________ molar mass.
PROPERTIES OF GASES
- In order to fully describe a gas, four
measurable quantities must be stated.
* PRESSURE: ________________________________________________
units: 1 atm = _____ mm Hg = _____ torr = _____ kPa = _____ Pa
measured with a ___________________
* TEMPERATURE: ____________________________________________
units: degrees Celsius (oC), Kelvins (K), or oF (oF not usually used in class)
how to convert from oC to K?____________________________________
** “STP” stands for “Standard
Temperature and Pressure”. The
conditions at STP are exactly 1 atm pressure and
exactly 0 oC. **
* VOLUME: _________________________________________________
units: 1 Liter (L) = _____ mL = _____ cm3
= _____ dm3
* QUANTITY: _______________________________________________
units: moles how to convert
from grams to moles? __________________
