Kinetic Molecular Theory (KMT):
An attempt to explain gas behavior.
Temperature scale used in gas calculations. Has an absolute zero. °C + 273 = K
Force of gas molecules colliding with surfaces
Pressure due to the layers of air in the atmosphere
Standard Temperature and pressure:
1 atm (or anything it’s equal to) and 0°C (273 K)
All assumptions of the kinetic molecular theory are true.
Molar Mass (Molecular Mass):
Grams per mole for a molecule.
Mass per volume of a sample
Average Translational Kinetic Energy (KEave):
Average kinetic energy (energy due to motion) of each particle.
Root-Mean-Square Speed (Vrms):
One measure of average particle speed in a gas
Maxwell’s Probability Distribution:
Probability function that indicates the probability that a particle in a gas will be moving at a certain speed.
Real gases have significant particle volume and significant attractions/repulsions
The rate at which a gas travels through a container
The rate at which a gas escapes through a tiny hole
