Particle Theory of Matter Flashcards
Made up of extremely tiny particles in the same substance are made up same particles
Matter
attract one another these forces get stronger as the ? get closer
Particle
strong, small particle, little motion
Solid
medium, space is medium, vibrational and rational
Liquid
weak, large, vibrational and rational and translational
Gas
observe without changing the matter
physical change
tendencies of a substance
chemical change
property that depends on the amount of matter in a sample
extensive property
property of matter that depends only on the type of matter in a sample and not on the amount
intensive
manual separation
handpicking
separating without disturbing the lower liquid layer
decantation
separating undissolved solid from liquid using filter paper
filteration
big component to fine
sieving/sifting
by throwing the mixture in the air lifting the wind blows
winnowing
separationg metal to non-metal
use of magnet
liquidic evaporate, solid particle remain
evaporation
purifies liquid mixture by boiling points
distillation
separating to from stationary phase
chromatography
separating two liquids like oil and water
separatory funnel
periodic table
element
2 or more element
compound
mixed thoroughly, uniform, same nature
homogeneous
not truly mix, non-uniform
heterogeneous
the solid not dissolve in the liquid
suspension
somewhere between real solution and suspension
colloids
finely mixed
solution
is the measure of how quickly a specific materials capable of catching fire and burning. it occurs between the adjacent of neighboring molecules
flammablity
Law of conservation of matter
the number of atom doesn’t change, the mass must remains constant as well
1743-1794
Antoine Lavoisher
Law of Constant composition
always contains its component elemnts in fixed ratio(by mass)
1754-1826
Joseph Proust
Law of multiple proportion
the same two elements from more than one compounds, the different masses of one element that combine with the same mass of the other element are in the ratio of small whole number
1766-1844
John Dalton
John Dalton-Atomic Model (1808)
atoms are small, indisible, divided, crated, destroyed
an element= identical
