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?
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.
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:
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.
Pressure can be exerted by solids, liquids and gases.
TRUE
FALSE
The pressure of the gas in the balloon in the ice water will be:
Greater than that of the balloon in the boiling water.
Less than that of the balloon in the boiling water.
The same as that of the balloon in the boiling water.
Not enough information to answer the statement.
Weather balloons travel to a great height gathering data before the balloon bursts. This is because the atmospheric pressure (layer of gas surrounding the earth):
Increases the higher you travel.
Decreases the higher you travel.
Remains the same.
Not enough information to answer the question.
Which answer below describes two quantitative and two qualitative pieces of data about a cat
pointed ears, soft fur, large eyes, 4 legs
lots of whiskers, grey eyes, multicoloured fur, 2 ears
small mouth, 2 eyes, 4 legs, 2 ears
2 ears, 4 legs, round eyes, multicoloured fur
How long does diffusion last?
Until the concentration of particles in the system is equal
Until a region in the system has a smaller concentration of particles than the other
Until a region in the system has a greater concentration of particles than the other
Until the particles disappear from the system
