Pearson Science Year 7 Module 2.2: Solids, Liquids And Gases Quiz
What do you know about solids liquids and gases? Do you know how ice forms? Are there things you can't even view with a standard microscope? Are the particles in solids closely packed together, or are they dispersed? Did you know a particle is just a tiny portion of matter? Are the particles in gases spread out? Take this quiz and learn all about it!

Now that you have skimmed through the module and have a general idea of what it is about, it is time to read it in more detail. Each question in Part 2 contains one or more sentences from the which have missing words. Read the module in more detail to find the missing words. - 2.This part of your homework will check your understanding of the module.
- 3.Look at Figure 2.2.4 on pg 54. What do you think this diagram tells you about solids.
- 4.Look at Figure 2.2.5 on pg 54. What do you think this diagram tells you about liquids?
- 5.In this part of the homework you are required to write full sentence answers to the questions.
- 6.
For each of the pictures shown below state if it represents a solid, liquid or gas. Also give an explanation for your choice.
- 7.Look at Figure 2.2.6 on pg 55. What do you think this diagram tells you about gases?

Your Science text book contains a lot of detailed information. If you try to absorb all of the information in one go you can easily get lost or confused. We recommend that you skim the text first. One way to do this is to look at the pictures and diagrams before reading the chapter in detail. This gives you some clues about what the information text contains. You then look at the detail later.

This part of your homework is designed to help you remember the essential science terminology from this chapter.
- 10.Which of the following ideas are used in the particle model?
- A.
All substances are made up of tiny, hard particles that are too small to see.
- B.
All substances are made up of large, soft particles similar to marshmallows.
- C.
The particles of substances do not move because they have no energy.
- D.
The particles of substances always have energy and are moving (even if it is a very small amount).
- E.
The particles of substances move about more and move faster as temperature is increased
- F.
The particles of substances move about less and move slower as temperature is increased
- G.
The closer the particles are to one another, the stronger the attraction between them.
- H.
The closer the particles are to one another, the weaker the attraction between them.
- 11.The particles in a solid have energy and [Blank] about as shown in Figure 2.2.4. The particles don't break out of position but just [Blank] about on the spot.
- 12.If you increase the temperature, this gives the particles more [Blank] and so they [Blank] more.
- 13.
Explaining solids The particles in solids are closely packed in [Blank] positions. Forces between neighbouring particles form bonds that [Blank] all the particles in the solid closely together.
- 14.
Explaining liquids In a liquid, the particles are still packed closely together but they are far more [Blank] [Blank] (joined) to their neighbours than the particles are in a solid. The loose bonding allows the particles to [Blank] about and over each other, allowing the liquid to [Blank], drip and fill the bottom of whatever [Blank] it is in.
- 15.If a particle has lots of [Blank], then it will move about a lot. If the particle has very little energy, then it will move about only a [Blank] bit.
- 16.You add energy to matter whenever you [Blank] it, as heat is a type of [Blank].
- 17.As the liquid is [Blank], this movement gets [Blank].
- 18.
Explaining gases The particles of gases are spread far [Blank] and have [Blank] holding their particles together.
- 19.This lack of bond between particles allows them to move [Blank] and in straight lines until they [Blank] something. The particles could hit other gas [Blank] or the [Blank] of the container they are in.
- 20.The Particle Model (Page 53) In the particle model, all substances are thought to be made of incredibly small, hard [Blank] called particles. Each ball has energy and [Blank] according to how much [Blank] it has.
- 21.The more you [Blank] a substance, the more energy the particles get and the [Blank] they move. If you [Blank] a substance, then the reverse happens: the particles move about [Blank] and move more slowly.
- 22.The particle model uses the following ideas:
- All substances are made up of tiny [Blank] that are too small to see even with a normal microscope.
- Even if it is a very small amount, the particles always have energy and are [Blank].
- The particles move about more and move faster as [Blank] is increased.
- The closer the particles are to one another, the stronger the [Blank] between them.
- 23.Which of the following statements about solids are correct?
- A.
The particles in solids are free to move about.
- B.
The particles in solids are closely packed together in fixed positions.
- C.
The particles in solids have energy and vibrate on the spot.
- D.
The particles in solids do not move at all. They don't even vibrate.
- E.
If you increase the temperature of a solid, the particles will vibrate less.
- F.
If you increase the temperature of a solid, the particles will vibrate more.
- G.
Solids have a fixed shape and do not flow because they're particles are strongly bonded to their neighbours.
- H.
Solids have a fixed shape and do not flow because they're particles are loosely bonded to their neighbours.
- I.
Solids are incompressible because they're particles are spread far apart
- J.
Solids our incompressible because their particles are packed closely together
- K.
Heating causes a solid to expand because the particles vibrate faster making them spread further apart.
- L.
Heating causes a solid to expand because the particles vibrate slower making them move closer together
- 24.Which of the statements about liquids are correct?
- A.
In liquids, the particles are still packed closely together but they are far more loosely bonded to their neighbours.
- B.
In liquids the particles are still packed closely together and they are also very tightly bonded to their neighbours.
- C.
The loose bonding of particles in a liquid allows them to move about and over each other.
- D.
The tight bonding of particles in a liquid allows them to move about and over each other.
- E.
As a liquid is heated, the movement of its particles decreases.
- F.
As a liquid is heated, the movement of its particles increases.
- G.
Liquids flow to take up the shape of the bottom of the container there in because the bonds between particles are loose enough to allow the particles to slip over one another.
- H.
Liquids flow to take up the shape of the bottom of the container there in because the bonds between particles a strong holding them in a fixed position.
- I.
Liquids are incompressible because their particles are far apart.
- J.
Liquids are incompressible because their particles are packed closely together.
- K.
Liquids expand when heated because the particles move over each other faster, making them spread further apart.
- L.
Liquids expand when heated because the particles move over one another slower, making them move closer together.
- 25.Which statements about gases are correct?
- A.
The particles in a gas spread far apart and have nothing holding them together.
- B.
The particles in a gas are packed close together and there are strong bonds between them.
- C.
The particles in a gas move fast and in straight lines until they hit something.
- D.
The particles in a gas don't move at all because they are so tightly bonded together.
- E.
Gas particles hitting the walls of the container cause pressure on the walls of the container.
- F.
Gas particles hitting the walls of the container have no effect on the container because the particles are so small.
- G.
Gas particles are spread so far apart that you cannot see the gas. Gases are often said to be invisible.
- H.
Gas particles are packed so closely together that they are very easy to see
- I.
Gas particles are packed so closely together that there is no space between them. This causes them to be incompressible.
- J.
Gas particles are spread so far apart that there is plenty of vacant space between them. This allows them to be compressible.
- K.
Because there are no bonds between gas particles they travel in all directions until they fill the container that they are in.
- L.
Because there are strong bonds between gas particles they remain in a clump in a small region of the container that they are in.
- M.
Heating causes gas particles to move slower making them move closer together. This causes gases to contract when heated
- N.
Heating causes gas particles to move faster making the move further apart. This causes gases to expand when heated.
