Boyle's law
Gas is inversely proportional to the applied pressure
Charles' Law
volume occupied by mass of a gas is directly proportional to it absolute temperature
Avogadro's law
at the same T & P equal volumes of 2 gases contain the same number of molecules (or moles as gas)
Ideal gas law
combo of boyle's charles' and avogadros
Dalton's Law
pressure exertged byu a mixture of gases is the sum of the parial pressures of the individual gases
Vapor pressure
pressure exerted by gas over the liquid at equilibrium
Diffusion
interminling of gases
effusion
gases pass through porous containers
gay-lusasac's law
at constant temp and Pressure the volumes of reacting gases can be expressed as a ratio of simple whole numbers
Solid and liquid molecules are
condensed atoms ions loecules are close to one another
highly incompressible
intermolecular forces
forces between indiviudal particles (atoms, molecules, ions) of a substance
intramolecular forces
a covalent bond and ionic bond w/in compounds
Molecules at surface tension are attracted how?
unevenly
surface tension
measure of the unequal attractions that occur at the surface of a liquid
Viscosity
resistance to flow
Capillary action
the drawing of a liquid up the inside of a small-bore tube when adhesive forces exceed cohesive foreces or
depression of the surface of the liquid when cohesive forces exceed adhesive forces
Evaporation
process in which molecules escape from the surface of a liquid
Miscibe
Mutually soluble
Immiscible
not mutually soluble. Do not mix together
ex oil and water
Polar bond have what kind of effect?!
ABNORMAL!!!
decomposition
vapor to solid
Exothermic
Sublimation
going from solid to gas
Endothermic
Condensation
gas or vapor becoming liquid
exothermic
Evaporation
liquid becoming gas or vapor
Endothermic
Melting
solid to liquid
endothermic
Freezing
liquid to solid
exothermic
Heat of vaporization
amount of heat required to change 1g of a liquid substance to a gas at constant T
Heat of condensation
Amount of heat required to change 1g of a gas to a liquid
molar heat of vaporization
amount of heat required to change 1 mol of a liquid to a gas at constant T
molar heat of condensation
amount of heat reqd to change of mol of a gas to liquid
lower MW lower boiling point
higher MW higher boiling point
normal melting point
Temp at which the solid metals at 1 atm of pressure
heat of fusion
amount of heat required to melt one gram of a solid at its melting point at constant T
heat of crystallization
amount of heat required to freeze one grams of its liquid at constant T
Polar liquid are miscible with other polar liquids
like dissolves like
polar gases are more soluble in h2o than nonpolar or less?
More
unsaturated
less than max
saturated
solutions have the maximum amount of solute in the solvent at sprcific temperature
supersaturated
solutions have higher concentrations of dissolved solutes than saturated
Ionic solids dissolve endothermically or exothermically
endothermically
pressure changes have little or no effect on solubility in liquid
pressure changes have large effects on the solubilitiy of gases in liquids
Colligative properties
solution properties that depend solely on the number of particles dissolved in the solution and not the kinds of particles dissolved
4 common types of colligative prop
vapor pressure lowering
freezing point depression
boing point elevation
osmotic pressure
Osmosis
net flow of solvent between two solutions separated by semipermeable membrance
Colloids
mixtures that have particle sizes between those of true solutions and suspensions
hydrophillic
water loving colloids many biological proteins
hydrophobic
water hating colloidsq
tyndall efect
colloids scatter light when it is shined upon them
