The document discusses mixtures and their properties. It states that a mixture maintains the individual properties of its substances and can be separated into its parts through physical changes. A homogeneous mixture looks the same throughout, while examples of mixtures include salt, water, and air.

1. 1. The different substances in a mixture
.
A. keep their individual properties
B. combine chemically
C. form new molecules
D. cannot be separated
2. A mixture that is the same through out, or is mixed so well it looks like one
substance is a
mixture.
A. homogeneous
B. heterogeneous
C. pure
D. man made
3. Mixtures can be separated into
by physical changes.
A. the individual atoms of the mixture
B. the individual parts of the mixture
C. new substances with new properties
D. the individual elements that make up the compounds of the mixture
4. Which of the following is a mixture?
A. sulfur
B. water
C. salt
D. air

3. • The process of separating a liquid's
components by heating it to the point
of vaporization and collecting the
cooled condensate (vapor that reverts
to liquid through condensation) in
order to obtain a purified and/or
concentrated form

5. OTHER USES
• Distillation is by far the most common
method of separation in the petroleum,
natural gas, and petrochemical industries.
Its many applications in other industries
include air fractionation, solvent recovery
and recycling, separation of light isotopes
such as hydrogen and deuterium, and
production of alcoholic beverages, flavors,
fatty acids, and food oils
