3. General properties of matter
Mass:mass is
the quantity the

than chalk
Brittleness:matter
is brittle when it
breaks easily.a
wooden bar is
more brittle than a

Elasticity:
matter is
elastic if it

Density:relation
ship between

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
