Matter is anything that has mass and takes up space. All objects around us like rocks, humans, air and water are made of matter. General properties of matter include mass, which is measured in kilograms and grams, and volume, which is the amount of space an object takes up and is measured in liters and milliliters. Specific properties are hardness, brittleness, elasticity, and density. Materials can also be described by their thermal conductivity, transparency, and impermeability.

3. General properties of matter
Mass:mass is
the quantity the
amount of
matter.
We measure
mass in
kilograms and
grams.
Volume: volumen is
the amount of
space an object
takes up.
We measure
volumen in litres
and millileters.we
use containes like
test

4. Specific properties of matter
Hardness: we
say matter is
hard when is
dificult to
scratch.metal
is harder
than chalk
Brittleness:matter
is brittle when it
breaks easily.a
wooden bar is
more brittle than a
metal is easily
Elasticity:
matter is
elastic if it
returns to is
original shape
Density:relation
ship between
mass and the
volumen of a
body for
example the
metal and the
clay

5. Properties of materials
Thermal conductivity:when a
material does not transmit
heat,we call insulator
Transparency:when a material
does not pass through ,we say
it is opaque
Impermeability: when a
material does not let liquid
pass through, we say it is
imermeability
