Matter Test Flashcards
Mass
a measure of the amount of matter the objects contain
Volume
an object is a measure of the space occupied by the object
Extensive Property
A property that depends on the amount of matter in a sample
Intensive Property
A property that depends on the type of matter in a sample, not the amount of matter.
Substance
Matter that has a uniform and definite composition
Solid
Form of matter that has definite shape and volume
Liquid
A form of matter that has indefinite shape,flows,yet still has a fixed volume
Gas
A form of matter that takes both the shape and volume of its container
Vapor
A gaseous state of a substance that is generally a liquid or solid at room temperature, as in water vapor.
Physical Change
Properties of material change but the composition of a material does not change
Chemical Change
Properties of a material change and so does the composition
Mixture
A physical blend of two or more components.
Heterogeneous Mixture
A mixture in which the composition is not uniform throughout
Homogeneous Mixture
A mixture in which in which he composition the composition is uniform throughout
Solution
A liquid mixture within a major component.
colloid
A mixture in which very small particles of one substance are distributed evenly throughout another substance
Phase
Any part of a sample with uniform composition and properties
Filitiration
The process that separates a solid for of the liquid in a heterogeneous mixture
Distillation
A way to separate water from the other components in tap water
Element
Simplest form of matter that has a unique set of properties
Compound
It the substance that contains two or more elements chemically combined in a fixed proportion
Chemical Property
The ability of a substance to undergo a specific chemical change
Chemical Reaction
One or more substances change into one or more new substances
Reactant
A substance present at the start of a reaction
Product
A substance produced in a reaction
Precipitate
A solid that forms and settles out of a liquid mixture
Law of Conservation of Mass
In any physical change or chemical reaction, mass is conserved
