2. Physical change – matter changes in states
Matter can change or transform from one sate to another.
Appearance, from, shape, or size may be altered but the
composition stays the same or it does not change into a new
substance.
Example:
Water cycle
Dying a plain white t-shirt into new colors
Doing haircut
Molding clays into different characters or animals

3. Example of Physical Change
Aside from the changes in water:
1.Crushing a can – can just deformed
2.Mixing sand and water – it settled down due to water,
but still it can be back to its original form by
filtration.
3.Breaking of glass – it just turned into smaller pieces
but its still glasses.
4.Dissolving sugar in water - the dissolve sugar can
still be back to its original form by evaporating the
water.

6. Changes from gas or vapor to
liquid
It happens when the vapor
cools and then became water
Example:
Clouds, fog, and mist are
product of condensation.
Vapor condenses when
moist air is cooled below its
dew point
Also called as freezing
Changes from liquid to solid
It occurs when the temperature
is low
Different liquids have different
freezing point
Example:
Water (liquid) to ice cubes/ice
Juices to ice candy
