They have no fixed shape but they do have a fixed volume.
They have no fixed shape and no fixed volume.
The particles of solids ________________
vibrate about their fixed postions
are able to slide over each other
move about freely at high speeds and in random direction
do not move
The particles of liquids ________________
vibrate about their fixed postions
are able to slide over each other
move about freely at high speeds and in random direction
do not move
The particles of gases ________________
vibrate about their fixed postions
are able to slide over each other
move about freely at high speeds and in random direction
do not move
These particles are held together by very strong forces of attraction
Solid
Liquid
Gas
Plasma
What happens to particles of liquid when they are heated?
They slide over one another faster and move further apart
They slow down and compress
They stop moving
They slide over one another slower and move closer together
The diagram represent the arrangement of particles in ____________.
gas
liquid
solid
The diagram represent the arrangement of particles in ____________.
gas
liquid
solid
Why does solid has a fixed shape?
The particles are held by very strong forces of attraction. They can only vibrate about their fixed position. Hence, they have an orderly arrangement.
The particles are held by weak forces of attraction. They can move rapidly in all directions. Hence, they have an disorderly arrangement.
The particles are held by strong forces of attraction. They can slide over one another. Hence, they have an disorderly arrangement.
