Total questions: 20
Worksheet time: 10mins
What are the three states of matter?
air, water, fire
solids, liquids, gases
ice, water, steam
USA, UK, UAE
Which of these materials will have the most
similar properties?
air, oxygen, ice
water, iron, air
iron, stone, wood
oil, water, wood
All liquids:
have a fixed volume and take the shape of their container.
have a fixed volume and a fixed shape.
will spread out until their volume has doubled.
can change their volume but not their shape.
Which are usually the most dense?
A
gases
liquids
solids
they are all the same
Evidence is:
anything that can be used as a weapon.
another word for a scientific idea.
the data collected in experiments.
a measure of how dense different solids are.
A theory is:
an idea that explains evidence.
the result of an experiment.
a chapter in a science book.
the instructions for doing an experiment.
How do scientists test theories?
They see if their friends agree with them.
Theories are always correct, so scientists do not need to test them.
They use the theory to make predictions, and do experiments to see if the predictions are correct
They look in a different book.
Which of these things would a theory about solids, liquids and gases not have to explain?
Why a sealed tin will explode if you heat it.
Why water flowing over waterfalls looks beautiful.
Why it is difficult to squash a solid.
Why liquids can flow.
1 Everything is made up of:
particles which are arranged differently in solids, liquids and gases.
particles which are arranged in the same way in solids, liquids and gases.
water particles.
nothing.
In a solid:
the particles are very close together.
the particles are as far apart as possible.
the particles are quite close together.
there are no particles.
In a liquid, the particles are held together by weak:
bombs.
bands.
bonds.
particles.
A gas can be squashed because:
the particles are held tightly in place.
there are no particles.
the particles are far apart.
the particles are squashy.
If you put a drop of coloured liquid into a glass of cold water and leave it to stand without stirring, the colour spreads through the water. This is called:
divination.
dissolving.
dissuasion.
diffusion.
Which of these is a prediction:
Michael came home at 6 p.m.
Michael uses his watch to find out when it is 6 p.m.
Michael likes to eat at about 6 p.m.
Michael should be home at 6 p.m.
How fast do things spread out in liquids compared with in gases?
They spread out faster in liquids.
They spread out faster in gases.
They spread out at exactly the same speed.
They do not spread out in liquids at all.
If you put some sugar into cold water and leave it without stirring, the sugar will eventually dissolve and mix with the water. This happens because:
A
particles are extremely small.
particles in a liquid are always moving around.
water particles are bigger than sugar particles.
sugar particles are bigger than water particles.
Pressure in a container full of gas is caused by:
particles sticking to the walls.
particles bumping into the walls.
particles sticking to each other.
particles falling to the bottom of the container.
You can increase the pressure in a container full of gas by:
making the container smaller.
making the container bigger.
cooling the gas.
taking some of the gas out.
If you put more gas into a container the pressure increases because:
the particles all cool down.
there is more space for the particles to move around.
more particles fall to the bottom of the container.
there are more particles, so there are more collisions with its walls.
The air is being sucked out of this bottle. Why is it collapsing?
There is more pressure inside than outside.
There is more pressure outside than inside.
There are more particles inside it.
Air particles are sticking to the walls and pulling them in.
