viscosity
answer
a measure of the resistance of a liquid to flow
question
surface tension
answer
the energy required to increase the surface area of a liquid by a given amount
question
pressure
answer
force per unit area
question
kinetic-molecular theory
answer
the model describing the behavior of gases in terms of particles in motion MOTION MOTION MOTION ROLLERCOASTERS
question
barometer
answer
an instrument used to measure atmospheric pressure
question
temperature
answer
a measure of the average kinetic energy of the particles in a sample of matter weird ass definition
question
Dalton's law of partial pressure
answer
states that the total pressure of a mixture of gases is equal to the sum of the pressures of each gas in the mixture TOTAL PRESSURE OF MIX IS EQUAL TO SUM OF PRESSURE OF EACH GAS wtf isnt that common sense?
question
melting point
answer
the temperature at which a crystalline solid becomes a liquid we _posicle
question
vapor pressure
answer
the pressure exerted by a vapor over a liquid
question
phase diagram
answer
a graph that shows in which phase a substance exists under different conditions of temperature and pressure
question
elastic collisions
answer
collisions between gas particle in which no kinetic energy is lost rubber bands
question
diffusion
answer
the movement of one material through another a perfume _______throughout the air in the room to the other side
question
deposition
answer
SUBSTANCE CASE (U DOESNT COME BEFORE O!!) the process by which a substance changes from a gas or vapor to a solid without first becoming a liquid depose to go from gas to vapor without becoming liq first otherwise it'd just be called pose. LOL
question
crystalline solid
answer
a solid whose atoms ions or molecules are arranged in an orderly geometric three dimensional structure
question
freezing point
answer
temperature at which a liquid becomes a crystalline solid
question
Graham's law of effusion
answer
states that the rate of effusion for a gas is inversely proportional to the square root of its molar mass that stupid stuff with all those damn numbers we did on friday diff/eff? ring a f*cking bell?
question
boiling point
answer
temperature at which the vapor pressure of a liquid equals the external or atmospheric pressure WHEN DA STEAM EQUALS ROOM TEMPERATURE?!?! OMFG IM SO SMAHT
question
sublimation
answer
SOLID CASE (O COMES BEFORE U!!) the process by which a solid changes directly to a gas without first becoming a liquid s for subl....
question
amorphous solid
answer
a solid in which the particles are NOT arranged in regular, repeating pattern that weird asss word that looks like the word amphibian
