is used to refer to a
specific kind of matter such as wood, steel, nickel, marble,
concrete, and milk
Material
A material is not uniform
throughout
Heterogeneous
examples of heterogeneous materials:
Granite, Wood
A material that consists of only one phase
Homogeneous
Examples of Homogeneous Mixtures
saltwater, glass
contains more than one kind of material.
Mixture
a homogeneous mixture that does not
have any composition variation
Solution
Major components of any mixture
Solute, solvent
materials which always have the same composition
Substances
Element
composed on only one kind of atom
made of more than one kind of atom
Compound
The physical properties can also be further subdivided into
Extensive, Intensive
The properties of a substance can be divided into two classe
Chemical, and physical properties
Extensive properties
depend on the amount of material
Intensive properties
depend upon the nature of material
Physical change
affect on the physical properties of material
Chemical change
produce new substances with new properties
Extensive properties examples
weight, mass, volume
Intensive properties examples
Temperature, Boiling Temperature, Pressure
what is a physical property of matter
a trait that can be observed and measured without changing the chemical identity of a substance
Define extensive property
An extensive property is a property that depends on the amount of matter in a sample
Define intensive property
An intensive property is a property of matter that depends only on the type of matter
How do mixtures and substances differ
something that contains only one kind of matter, but take two or more pure substances and mix them together, its a mixture
What is a chemical property
characteristic or behavior of a substance that may be observed when it undergoes a chemical change or reaction, EX: The ability of iron to form rust when combined with air
