Correct Answer(s)
A. All substances are made up of tiny, hard particles that are too small to see.
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
G. The closer the particles are to one another, the stronger the attraction between them.Explanation
The correct answer choices for this question are: "All substances are made up of tiny, hard particles that are too small to see," "The particles of substances always have energy and are moving (even if it is a very small amount)," "The particles of substances move about more and move faster as temperature is increased," and "The closer the particles are to one another, the stronger the attraction between them." These ideas are used in the particle model to explain the behavior and properties of substances. The model assumes that all substances are composed of tiny, hard particles that are too small to see, and that these particles are constantly in motion, even if the motion is very small. Additionally, the model explains that as temperature is increased, the particles move about more and faster, and that the closer the particles are to each other, the stronger the attraction between them.Rate this question:

If a particle has lots of ________, then it will move about a lot. If the particle has very little energy, then it will move about only a ________ bit.
Correct Answer(s)
energy
little, tinyExplanation
If a particle has lots of energy, it will have a high level of kinetic energy, allowing it to move about a lot. On the other hand, if the particle has very little energy, it will have a low level of kinetic energy, causing it to move about only a tiny bit.Rate this question:
- 16.
You add energy to matter whenever you ________ it, as heat is a type of ________.
Correct Answer(s)
heat
energyExplanation
When you add heat to matter, you are actually adding energy to it. Heat is a form of energy transfer, where energy is transferred from a hotter object to a cooler object. So, by adding heat to matter, you are increasing its energy content.Rate this question:
- 17.
As the liquid is ________, this movement gets ________.
Correct Answer(s)
heated
faster, greater, moreExplanation
When the liquid is heated, its molecules gain energy and move faster. This increase in molecular motion leads to a greater movement of the liquid as a whole. Therefore, the correct answer is "heated, faster, greater, more."Rate this question:
- 18.
Explaining gases The particles of gases are spread far ________ and have ________ holding their particles together.
Correct Answer(s)
apart
nothingExplanation
Gases have particles that are spread far apart from each other and have nothing holding their particles together. This is because gases have weak intermolecular forces and high kinetic energy, allowing the particles to move freely and independently. Unlike solids and liquids, gases do not have a definite shape or volume and can easily expand and fill the space available to them.Rate this question:
- 19.
This lack of bond between particles allows them to move ________ and in straight lines until they ________ something. The particles could hit other gas ________ or the ________ of the container they are in.
Correct Answer(s)
fast, faster
hit
particles, molecules, atoms
walls, sidesExplanation
Particles in a gas lack strong bonds with each other, which allows them to move rapidly and in straight lines until they collide with something. These particles, which can be molecules or atoms, may hit other gas particles or the walls/sides of the container they are in.Rate this question:

The more you ________ a substance, the more energy the particles get and the ________ they move. If you ________ a substance, then the reverse happens: the particles move about ________ and move more slowly.
Correct Answer(s)
heat
faster
cool
lessExplanation
When you heat a substance, the particles gain more energy and move faster. This is because heat increases the kinetic energy of particles, causing them to move more rapidly. On the other hand, when you cool a substance, the reverse happens. The particles lose energy and move about less, resulting in slower movement.Rate this question:
- 22.
The particle model uses the following ideas:
- All substances are made up of tiny ________ 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 ________.
- The particles move about more and move faster as ________ is increased.
- The closer the particles are to one another, the stronger the ________ between them.
Correct Answer(s)
particles
moving
temperature
attractionExplanation
The particle model is based on the idea that all substances are made up of tiny particles that are too small to see, even with a normal microscope. These particles are always in motion and have energy, regardless of the amount. The speed and movement of the particles increase as the temperature is increased. Additionally, the closer the particles are to each other, the stronger the attraction between them.Rate this question:

- L.
Heating causes a solid to expand because the particles vibrate slower making them move closer together
Correct Answer(s)
B. The particles in solids are closely packed together in fixed positions.
C. The particles in solids have energy and vibrate on the spot.
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.
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.Explanation
Solids are characterized by closely packed particles that are fixed in position. These particles have energy and vibrate in place. When the temperature of a solid is increased, the particles vibrate more vigorously. Solids have a fixed shape because their particles are strongly bonded to their neighbors, and they do not flow. Solids are incompressible because their particles are packed closely together. Heating a solid causes the particles to vibrate faster, leading to an expansion as they spread further apart.Rate this question:

A. In liquids, the particles are still packed closely together but they are far more loosely bonded to their neighbours.
C. The loose bonding of particles in a liquid allows them to move about and over each other.
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.
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.Explanation
Liquids have particles that are still packed closely together, but they are more loosely bonded to their neighbors. This loose bonding allows the particles to move about and over each other, which is why liquids flow and take up the shape of the container. As a liquid is heated, the movement of its particles increases, causing them to spread further apart and making the liquid expand. Liquids are incompressible because their particles are packed closely together, meaning they cannot be easily compressed.Rate this question:

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

A. The particles in a gas spread far apart and have nothing holding them together.
C. The particles in a gas move fast and in straight lines until they hit something.
E. Gas particles hitting the walls of the container cause pressure on the walls of the container.
G. Gas particles are spread so far apart that you cannot see the gas. Gases are often said to be invisible.
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.
N. Heating causes gas particles to move faster making the move further apart. This causes gases to expand when heated.Explanation
Gases are composed of particles that are spread far apart and have no bonds holding them together. These particles move rapidly in straight lines until they collide with something, causing pressure on the walls of the container. The particles in a gas are so spread out that they cannot be seen, making gases appear invisible. Gases are compressible because there is plenty of vacant space between the particles. Without any bonds between them, gas particles travel in all directions until they fill the container. Heating a gas causes the particles to move faster and further apart, resulting in expansion.Rate this question:
