Matter,Particles,changes of State,physical And Chemical Properties Flashcards
What is the physical property: how much light can pass through an object
Clarity
What is the physical property: the smell a object gives off
Odour
What is the physical property:solid liquid or gas
State
What is the physical property:how shiny or dull a object is
Lustre
What is the physical property:the ability to be hammered or bent
Malleability
What is the physical property: the ability to be drawn into thin wires
Ductility
Physical property(PP) or chemical property(CP) : Magnesium will react with acid to produce hydrogen gas
CP
Physical property(PP) or chemical property(CP) : Aluminum is very malleable
PP
Physical property(PP) or chemical property(CP) : Lead has a vet high density
PP
Physical property(PP) or chemical property(CP) : paper is a combustible material
CP
Physical change (P) or chemical change (C):the digestion of proteins in your stomach
C
Physical change (P) or chemical change (C):the evaporation of water produces clouds
P
Physical change (P) or chemical change (C):the dissolving of Kool aid crystals in water
P
Physical change (P) or chemical change (C):the burning of autumn leaves
C
What is the difference between physical and chemical properties
Chemical properties can be observed or measured when a substance undergoes a chemical change. Physical properties can be observed without a chemical change
What is the difference between physical and chemical changes
A physical change changes the appearance or form of the matter but the kind of matter in the substance does not. A chemical change changes the kind of matter and at least one substance with new properties is formed
What are five clues of a chemical change
1.colour change
2.precipitate is formed
3.bubbles
4.gives off heat/light
5.irreversible
What it the change occurring: gas to solid
Deposition
What it the change occurring: solid to gas
Sublimation
What it the change occurring:gas to liquid
Condensation
What it the change occurring:solid to liquid
Melting
What it the change occurring:liquid to solid
Solidification
What it the change occurring:liquid to gas
Evaporation
What is matter
A substance that has a mass and takes up space
What are the three states of matter
Solid liquid and gas
What are the two ways to classify matter
Pure and mixture
How can you tell if something is a pure form of matter
It cannot be separated by physical means
How can you tell if something is a mixture form of matter
It can be separated by physical means
What are the two types of mixtures
Homogenous and heterogeneous
