Cambridge Primary 5 Science: Solids, Liquids and Gases This lesson quiz helps learners compare solids, liquids and gases using shape, volume, flow and particle ideas.
Use the model. Which state has a fixed shape and fixed volume?
A
liquid
B
solid
C
solution
D
gas
Explanation
A solid keeps its own shape and volume.
Which state has a fixed volume but takes the shape of its container?
A
gas
B
solid
C
liquid
D
powder only
Explanation
A liquid flows and takes the container shape while keeping volume.
Which state spreads to fill all the available space?
A
crystal
B
solid
C
liquid
D
gas
Explanation
Gas particles move freely and spread out.
Which material is most clearly a liquid at room temperature?
A
water
B
wood
C
steel
D
oxygen
Explanation
Water is a liquid at ordinary room temperature.
Which material is most clearly a gas at room temperature?
A
glass
B
air
C
ice
D
sand
Explanation
Air is a mixture of gases.
Which statement about particles in a solid is correct?
A
They are very far apart and fill the room
B
They have no movement at all
C
They are close together and vibrate in place
D
They flow past each other freely
Explanation
Solid particles are closely packed.
Which statement about liquid particles is correct?
A
They are fixed in a regular pattern only
B
They do not exist
C
They are always far apart
D
They are close but can move past each other
Explanation
This explains why liquids flow.
Which statement about gas particles is correct?
A
They are far apart and move freely
B
They always form crystals
C
They cannot be compressed
D
They are locked in place
Explanation
Gas particles have large spaces between them.
Why can a gas be compressed more easily than a liquid?
A
Gas particles are larger
B
There is more space between gas particles
C
Liquids have no particles
D
Gases are always colder
Explanation
Compression reduces the spaces between gas particles.
A material can be poured and forms a level surface. What state is it likely to be?
A
gas only
B
solid block
C
liquid
D
magnet
Explanation
Liquids flow and settle with a level surface.
A balloon becomes bigger as air is added. Which idea explains this?
A
Air has no volume
B
Solids fill balloons
C
Liquids disappear
D
Gas takes up space
Explanation
The added gas occupies space inside the balloon.
Which property is shared by solids, liquids and gases?
A
They are made of particles
B
They all fill every container completely
C
They all cannot be weighed
D
They all keep a fixed shape
Explanation
All matter is made of particles.
Which is not a state of matter in this lesson?
A
gas
B
shadow
C
liquid
D
solid
Explanation
A shadow is an absence or blocking of light, not matter.
Which item contains matter in all three states?
A
an empty shadow
B
a dry pencil only
C
a glass with ice, water and water vapour above it
D
a metal spoon only
Explanation
Ice is solid, water is liquid and vapour is gas.
Why does perfume smell spread through a room?
A
The smell has no particles
B
Liquids freeze the smell
C
Solids pull the smell
D
Gas particles move and diffuse
Explanation
Gas particles spread from high concentration to low concentration.
What happens to the volume of a liquid when it is poured into a new container?
A
It stays about the same
B
It becomes zero
C
It fills the whole room
D
It always doubles
Explanation
A liquid has a fixed volume.
Which state is easiest to describe by saying "no fixed shape and no fixed volume"?
A
solid
B
gas
C
crystal
D
liquid
Explanation
Gases take both the shape and volume of their container.
Why is sand tricky to classify by observation?
A
It has no particles
B
It cannot be touched
C
It pours like a liquid but each grain is a solid
D
It is always a gas
Explanation
Granular solids can flow as many small solid pieces.
Which test best distinguishes a gas from a liquid?
A
Check if it is natural
B
Check if it is useful
C
Check if it has colour only
D
Check whether it expands to fill the whole container
Explanation
Gases fill the available volume.
Which summary is correct?
A
Solids keep shape, liquids flow, gases spread out
B
Only solids are made of particles
C
Liquids and gases are the same
D
All matter keeps a fixed shape
Explanation
This compares the three states accurately.
