SOLIDS, LIQUIDS AND
GASES
An introduction to
different phase
changes of matter
and their examples
SOLID LIQUID GAS
Arrangement of Molecules in Matter
MOLECULES ARE
TIGHTLY PACKED.
MOLECULES ARE NOT
AS CLOSELY PACKED AS
IN SOLIDS.
MOLECULES ARE FAR
APART WITH LARGE
INTERMOLECULAR
SPACES BETWEEN
THEM.

Learning Outcomes
Some solids like salt and sugar are soluble 
in water. Their molecules spread themselves 
between the molecules of water.
Some liquids like milk, glycerine and 
lemon juice also dissolve in water. 
The liquids that mix with each other 
are called m i s c i b l e liquids. Liquids like 
oil and kerosene that do not dissolve in ‘
water are called i m m i s c i b l e liquids.

Solids, Liquids and Gases in
Water
Oxygen, carbon dioxide, and
nitrogen can dissolve in water.
Aquatic animals breathe oxygen,
while aquatic plants use dissolved
carbon dioxide for food. Carbon
dioxide is dissolved in soft drinks to
create fizziness. When water is
boiled, dissolved gases form
bubbles that separate from the
water.
