T1.1.1 Solids, liquids and gases Quiz: KS3 Chemistry, Unit 1

The 20 questions

1. In a solid, how are the particles arranged?

   • Spread out at random and moving in straight lines between collisions with the walls
   • Moving freely and far apart from each other, with no fixed positions for the particles
   • Sliding past each other while staying close together in a loose, disordered cloud
   • Fixed in position in a regular pattern, vibrating about their places

2. Which state of matter has particles that are close together but able to move past one another?

   • Liquid
   • Solid
   • Gas
   • Mixture

3. Which state of matter has particles that are far apart and move quickly in all directions?

   • Element
   • Solid
   • Liquid
   • Gas

4. What does the particle model say about the particles in a gas?

   • They move randomly with large spaces between them
   • They are fixed in place and cannot move, so the gas keeps its own shape
   • They touch each other at all times and have no space between them
   • They are held in a fixed, regular pattern that does not change with temperature

5. Why can a gas be compressed much more easily than a solid?

   • Its particles are bonded together very strongly into fixed, rigid groups of atoms
   • Its particles are arranged in a fixed pattern that stops them moving closer together
   • Its particles are larger than particles in a solid, so they take up more room
   • Its particles are far apart, so there is a lot of empty space between them

6. Why do liquids take the shape of their container?

   • Their particles are fixed in a rigid lattice
   • Their particles do not move at all
   • Their particles can move past one another
   • Their particles are much heavier than solid particles

7. Which property do solids have because their particles are closely packed in fixed positions?

   • They flow freely when they are poured
   • They can be compressed easily into a smaller volume
   • They keep a fixed shape and a fixed volume
   • They spread out to fill any container they are in

8. Which statement correctly compares gases with solids?

   • Gases cannot be compressed at all
   • Gases are much denser than solids of the same substance
   • Gases have a fixed shape and a fixed volume
   • Gases spread out to fill the whole of their container

9. A metal spoon keeps its shape when it is picked up. Which particle arrangement best explains this?

   • Particles far apart and moving rapidly in all directions, with large gaps between
   • Particles that stay still until the spoon is heated and then start to move apart
   • Particles held in fixed positions, packed closely together
   • Particles free to slide past each other, packed closely together but not fixed

10. Equal masses of water and water vapour are in separate sealed containers. Which statement is correct?

    • Both substances have particles that are fixed in position in a regular lattice
    • The vapour particles are much further apart than the water particles
    • The water particles are much further apart than the vapour particles, which are packed tightly
    • The vapour has a fixed shape and volume, but the liquid water does not keep a fixed shape

11. A student writes that particles in a liquid are fixed in place and vibrate. What is wrong with this?

    • Liquid particles have no mass at all, so they cannot be measured on a balance
    • Liquid particles do not vibrate at all and are held completely still in one place
    • Liquid particles are much larger than gas particles, which makes them heavier
    • Liquid particles are not fixed and can move around each other

12. Which state of matter is most easily compressed?

    • Solid
    • Liquid
    • Gas
    • Metal

13. A student models the particles in a solid with marbles touching one another in a grid. What does the model show?

    • Particles far apart and moving in random directions, with large gaps between them
    • Particles held close together in a regular arrangement
    • Particles that can roll freely past one another with no fixed arrangement at all
    • Particles with no connection to each other, so the sample has no fixed shape

14. Which property shows that gases have particles with large spaces between them?

    • Gases are much less dense than solids and liquids
    • Gases always have a fixed volume that does not change when the container is larger
    • Gases have particles that are fixed in place and vibrate about regular positions
    • Gases cannot flow through a pipe because their particles are too tightly packed

15. Which statement about solid particles compared with gas particles is correct?

    • Solid and gas particles are both fixed in position and only vibrate slightly
    • Solid particles move freely; gas particles vibrate in place about fixed positions
    • Solid particles are further apart than gas particles, which are packed tightly
    • Solid particles vibrate in place; gas particles move freely with large gaps

16. A solid, a liquid and a gas each contain the same substance. Which has the particles most tightly packed?

    • The solid
    • The gas
    • The liquid
    • All three are equally packed

17. Why does a gas have no fixed volume?

    • Its particles are far apart and move freely, so they spread to fill any space
    • Its particles are larger than those in a liquid, so they fill the container less
    • Its particles are bonded to form a rigid frame that holds the same volume always
    • Its particles are fixed in place, so the volume changes with the shape of the container

18. A substance has particles that are close together and move past each other. What can be inferred about its shape and volume?

    • It has a fixed shape but no fixed volume, so it can be squashed into a smaller space
    • It has a fixed shape and a fixed volume, like a solid with rigid particles
    • It has a changeable shape but a fixed volume
    • It has no fixed shape and no fixed volume, so it spreads out to fill its container

19. Which change would most reduce the space between gas particles in a sealed container?

    • Opening the container to the room so the gas can spread out into the air
    • Adding more air to the container so there are more particles in the same volume
    • Compressing the gas into a smaller volume
    • Warming the gas at constant volume so the particles move faster and spread out

20. Which of these most clearly shows that gas particles are moving?

    • A scent from an opened bottle slowly spreads across a room
    • A sugar lump stays in its bowl without moving or changing shape at all
    • A solid block keeps its shape on a table even when it is moved to a new room
    • A liquid forms a flat surface in a dish and does not spread out into the air
