Physical Properties Of Matter Flashcards
Physical property
Without changing identity of the substance
Ex colour, temp, density
Chemical property
Change of a substance to form others
Ex biodegradability
Solid
Particle spacing
Holds a particular shape
Definite volume
Density not affected by pressure
Liquid
Particle spacing
Does not hold own shape Flows freely Takes shape of container Occupies a definite volume High density and barely affected by pressure
Gas
Particle spacing
No definite shape or volume
Expands to fill a container or void
Density low
Greatly affected by pressure
Plasma
Particle spacing
Gaseous mixture of positive ions and electrons
Unstable particles
Common form of matter in universe
Least common on earth
Amorphous Material
Irregular arrangement of particles
Do not have definite melting point
Ex pb, cotton candy, rubber, glass
Liquid Crystal (LCD)
Like solids and liquids
Change appearance of colour when temp or electrical potential is changed
Phase Change
Conversions between states
Called phase transitions or changes of state
Melting
Solid to liquid
Ex Ice to water
Freezing
Liquid to solid
Ex water to ice
Sublimation
Solid to gas
Ex dry ice
Deposition
Gas to solid
Ex frost on a car
Condensation
Gas to solid
Ex water on a cold drink glass
Vapourization
Liquid to gas
Occurs throughout liquid at boiling point
