Moles
a number to count very small things
What is a mole
Attempts to explain the properties of gases
What is the kinetic molecular theory
the measure of the average kinetic energy of the particles
What is temperature
weak forces that result from temporary shifts in the density of electron clouds
What are dispersion forces
Requires enormous pressure, produces a small volume change
what is compression
6.02x10^23
what is avagadros number
An imaginary gas that follows the assumptions
As temperature goes down, the particles slow down
What is absolute zero
attraction between opposite-charged regions
What are dipole-dipole forces
less fluid than gases
what is fluidity
individual elements
What is an atom
particulates that are small and separated by empty space
What are assumes
Due to the large amount of space between the particles in the gas
What is low density
a special type of dipole-dipole attraction that happens between molecules
What is a hydrogen bond
stronger than the intermolecular forces, increases with mass and decreases with temperature
what is viscosity
for atoms with a charge
what is an ion
Occurs when the collision of gas particles with the walls of their container
What is gas pressure
gases expand to fill their containers
what is compression and expansion
take the shape of any container but have a fixed volume
What is a liquid
measure of inward pull by particles to the interior liquid
what is surface tension
Covalently bonded compounds (nonmetal and nonmetal)
what are molecules
measure using a barometer or a manometer
what is pressure
the escape of a gas through a tiny hole
What is effusion
Higher in liquid cause particals are held together
What is density
movement up a narrow gladd tube
what is capillary action
