Matter Flashcards
any physical substance that possesses mass
and occupies space (volume),
Matter
amount of matter in an object.
Mass
amount of earth’s gravitational pull on a certain
object.
Weight
more massive objects –
more gravitational pull – heavier
amount of space an object occupies.
Volume
true or false
All matter is made up of tiny particles
true
true or false
not all matter is made up of tiny particles
false
true or false
not all particles of one substance are the same.
false
true or false
All particles of one substance are the same.
true
true or false
Different pure substances are made of different particles.
true
true or false
Different pure substances are made of the same particles.
false
true or false
Particles are always moving.
true
true or false
Particles are always constant.
false
true or false
There are attractive forces between particles.
true
true or false
There are no attractive forces between particles.
false
what are the phases of matter
SOLID
LIQUID
GAS
PLASMA
BOSE-EINSTEIN CONDENSATE
Densely-packed particles of matter
SOLID
this matter’s attractive forces are very strong
SOLID
this matter’s particles are in fixed position
SOLID
Particles that are not as densely-packed as solids
LIQUID
this matter still exert attractive
forces
LIQUID
this matter has the ability to flow
LIQUID
Distance between particles of this matter is very high;
GAS
this matter have less attractive forces
GAS
this matter have the
highest freedom to move
GAS
William Crookes
PLASMA
Gas particles
tend to look like glowing jelly at
high temperatures
PLASMA
plasma is a Greek word that means
creature-like form
how is Bose-Einstein Condensate produced
when matter is cooled to extremely low temperature
achieved by
cooling an object close to absolute zero
BOSE-EINSTEIN CONDENSATE
conversion of a solid to liquid
melting
how is melting done?
when heat is added, the solid’s particles acquire energy and will have more freedom to move
temperature at which melting occurs
melting point
process where liquid turns solid
freezing
temperature where particles lose energy
freezing point
who are the discoverers of the Bose-Einstein Condensate
Wolfgang Ketterle
Eric Cornell
Carl Weiman
conversion of liquid into gas
vaporization
vaporization is also called
boiling
temperature at which a liquid boils or turns to gas
boiling point
cooling of gas particles, which slows down their speed
condensation
is it common for solids to turn into liquids before becoming a gas?
yes
happens when solids are converted to gases directly without having to go through the liquid state
sublimation
occurs when the energy of the particles in a solid and much higher than atmospheric pressure
sublimation
one way to achieve this is by rapidly raising the temperature of the solid beyond its boiling point
sublimation
another way to achieve this is by cooling a liquid under a vacuum, and then the solidified liquid turns to gas quickly
freeze drying
what are the examples of sublimation
solid carbon dioxide
dry ice
mothballs
example of condensation
formation of droplets on the surface of eyeglasses
gas transforms directly into a solid without having to go through the liquid state.
deposition
occurs when the temperature of the gas is lower than the freezing point
deposition
solid to gas
sublimation
gas to solid
deposition
solid to liquid
melting
liquid to solid
freezing
gas to liquid
condensation
liquid to gas
evaporation
when matter cannot be physically separated
pure substances
when matter can be physically separated
mixtures
when pure substances cannot be chemically decomposed
elements
when pure substances can be chemically decomposed
compounds
when the composition of mixtures is not uniformed
heterogenous
when the composition of mixtures is uniformed
homogenous
what are the 4 elements
metals
non-metals
metalloids
noble gases
what are the two compounds
ionic
molecular
what are the two homogenouses
solution
colloid
what are the 4 solutions
acids
bases
salt solutions
alloys
what are the 2 heterogenouses
colloid
suspension
what does the homogenous and heterogenous have in common
colloid
physical change or chemical change
transformation of matter from one state to another that only changes the for of that matter
physical change
physical change or chemical change
size, color, density, and mass become different
physical change

physical change or chemical change
transform the reactants to products
