any physical substance that possesses mass
and occupies space (volume),

Matter

amount of matter in an object.

Mass

more massive objects –

more gravitational pull – heavier

what are the phases of matter

SOLID
LIQUID

PLASMA
BOSE-EINSTEIN CONDENSATE

How well did you know this?

Not at all

Perfectly

Densely-packed particles of matter

SOLID

How well did you know this?

Not at all

Perfectly

this matter’s attractive forces are very strong

SOLID

How well did you know this?

Not at all

Perfectly

this matter’s particles are in fixed position

SOLID

How well did you know this?

Not at all

Perfectly

Particles that are not as densely-packed as solids

LIQUID

How well did you know this?

Not at all

Perfectly

this matter still exert attractive
forces

LIQUID

How well did you know this?

Not at all

Perfectly

this matter has the ability to flow

LIQUID

How well did you know this?

Not at all

Perfectly

Distance between particles of this matter is very high;

GAS

How well did you know this?

Not at all

Perfectly

this matter have less attractive forces

GAS

How well did you know this?

Not at all

Perfectly

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 chopping of wood

physical change

physical change or chemical change cutting of paper

physical change

physical change or chemical change transformations of matter through chemical reactions

chemical change

physical change or chemical change transform the reactants to products

chemical change

physical change or chemical change burning

chemical change

physical change or chemical change rotting

chemical change

physical change or chemical change cooking
