A solid is the state of matter that has a definite shape and
The particles are very close together because they have a very
strong attraction for each other.
Since they are so close, they cannot move around. So they just
vibrate in place.
PROPERTIES OF SOLIDS
There are two types of solids: Crystalline and Amorphous.
TYPES OF SOLIDS
Particles in a repeated
pattern of rows
Particles have no special
Particles don’t move around Particles don’t move around
Ex: iron, diamond, ice Ex; glass, rubber, wax
EXAMPLES OF SOLIDS
A liquid is the state of matter that has a definite volume but
takes the same shape of its container.
The particles move fast enough to overcome the attraction of
The particles slide past each other.
PROPERTIES OF LIQUIDS
EXAMPLES OF LIQUIDS
All liquids have surface tension.
Surface tension – a force that holds together particles at the
surface of a liquid.
ST makes some liquids to form spherical drops (like water).
Liquids have different ST’s than each other.
EXAMPLES OF SURFACE TENSION
Water Rubbing alcohol
All liquids have viscosity.
Viscosity – a liquid’s resistance to flow
The viscosity of a liquid depends on the attraction between
Ex: Water has a low viscosity, and that is why we have rivers.
Honey has a high viscosity be cause it takes forever to flow.
EXAMPLE OF VISCOSITY
A gas is the state of matter that has no definite shape or
Particles in a gas move quickly enough they can break away
from their attraction for other particles.
The amount of empty space between gas particles can
