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

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 ________________

These particles are held together by very strong forces of attraction
Solid
Liquid
Gas
Plasma
Arrange the strength of the forces of attraction between the particles of solids, liquids and gases from the strongest to weakest
(strongest) gases > liquids > solids (weakest)
(strongest) solids > liquids > gases (weakest)
(strongest) gases > solids > liquids (weakest)
(strongest) solids > gases > liquids (weakest)
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

Why solids and liquids cannot be compressed?
The particles are closely packed together and there are no empty spaces.
The particles are far apart from one another and there are empty spaces.
The particles are arranged in an orderly manner.
The particles are not arranged in an orderly manner.
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.
The three states of matter are represented by diagrams X, Y and Z. Which change occurs during condensation?
X to Y
X to Z
Y to X
Z to X
When ice melts...
The mass of the water decreases during melting.
The mass of the water stays the same before, during and after melting.
The mass of the water is always changing.
The mass of the water increases during melting.
When a liquid becomes a solid, what are the changes in the behaviour of the particles? Select all that apply.
Particles lose energy
Particles are unable to overcome forces of attraction
Particles move closer together
The volume decreases
Particles become smaller
What are the differences between steam and water vapour? Select all that apply.
Steam is formed through boiling, water vapour is formed through evaporation
Steam has greater kinetic energy than water vapour
Steam is formed at the boiling point, water vapour can be formed at temperatures below the boiling point.
