Matter Flashcards
Everything that occupies space and has mass
Matter
The smallest particle
Atom
2 categories abt matter based on particle
Mixture and pure substance
2 grps of pure substance
Element and compounds
It contains solute and solvent
All substances can be combined
Can be separated through physical means
Mixture
Can’t be separeated by physical and chemical means
All elements has its own properties and own atom
Pure substance
4 properties of solids
Amor DeCryMe Amorphous solids Density Crystalline solids Metallic solids
Ratio of mass per unit vol
Solids always sink because of intanct molecules
Density
3d, its atoms,ions,or molecules are arranged in an orderly,geometric 3d structure
Individual pieces are called crystals
Crystalline solids
Malleable(easily hammered into shapes)
Ductile(easily drawn into wires)
Consist of posotive metal ions
Metallic solids
Brittle
Forms when molten rock cools
Amorphous solids
- all matter, solid,liquid, gas are made up of tiny particles called atoms
- particles are in constant random motion
- particles hace KE and their motion increases as they gain energy
Kinetic Molecular Theory (KMT)
6 properties of liquids
FluViTeSuCaDe Fluidity Viscosity Temperature Surface tension Capillary action Density
The ability to flow
Fluidity
How liquids flow
Viscosity
Higher _____= higher KE
Temperature
The energy req to increase the surface area of a liquid by a given amount
Surface tension
Has 2 subj cohesion and adhesion
Climbing up of liquids
Capillary action
Forsmce of attraction between identical molecules
Cohesion
Force of attraction between different molecules
Adhesion
The greater the weight, the higher the ____
Density
3 properties of gas
TVP
Temperature
Volume
Pressure
Gases do not have definite ____
Gases fill whatever ___ is available
Measured by a burette
Volume
Gas are in continous motiom and they frequently strike the walls of their container
Si unit is :Pa (pascal)
Pressure
A measure of the average KE of the particles in matter
Higher ____= causes gas to expand
Higher ____= higher pressure
Temperature
4th state of matter
Plasma
A hot ionized gas that allows both + charged ion and - charged ion coexist
90% of matter in the universe is ___ state
Plasma
5th state of matter
Bose-Einstein condesate (BEC)
Refrigerated particles called bosons=low temp
By albert einstein and satyendra nath bose
Bose-eimstein condensate
