Solid Liquid Gas Quiz
Questions: 16 · 10 minutes
1. What is the change of state from a solid to a liquid called?
Freezing
Condensation
Melting
Sublimation
2. A pure solid is heated. Its temperature stops rising briefly while the solid turns into a liquid. What is happening to the supplied energy during this interval?
It is being used in the change of state rather than raising the temperature.
It is forcing the particles to stop moving completely.
It is being destroyed because the temperature is constant.
It is converting the material into a different chemical substance.
3. A gas is cooled but remains a gas. How does the average motion of its particles change?
The particles move faster because cold creates more space.
The particles move more slowly on average.
The particles stop moving completely as soon as cooling begins.
The particles become larger while keeping the same speed.
4. Which statement correctly describes a solid under ordinary conditions?
It has a definite volume but always expands to fill its container.
It has a definite shape but changes volume to fill its container.
It changes shape and volume to fill its container.
It has a definite shape and a definite volume.
5. Dry ice changes directly from solid carbon dioxide into carbon dioxide gas. What is this process called?
Evaporation
Condensation
Sublimation
Deposition
6. A sealed syringe contains air. When the plunger is pushed inward, the air occupies less space. What best explains this?
Air particles shrink when pressure is applied.
Air particles disappear through the syringe walls.
There is space between gas particles, so they can be pushed closer together.
The air instantly changes into a liquid whenever it is compressed.
7. A tray of liquid water is placed in a freezer and becomes ice. Which change of state occurred?
Melting
Freezing
Evaporation
Sublimation
8. What usually happens when a liquid is poured from a bottle into a wide bowl?
It takes the bowl's shape while keeping approximately the same volume.
It keeps the bottle's shape and volume.
It expands to fill the entire bowl, including the space above it.
It keeps its shape but changes its volume.
9. A shallow puddle slowly disappears on a warm, dry day without boiling. Which process is mainly responsible?
Evaporation
Freezing
Condensation
Deposition
10. Why is it generally easier to compress a gas than a liquid?
Liquids contain no spaces at all between particles.
Gas particles have no mass.
Liquid particles are fixed in a rigid pattern.
Gas particles have much larger spaces between them.
11. Which description best represents particles in a liquid?
They are far apart and move independently throughout all available space.
They are locked into fixed positions and only vibrate.
They are close together but can move past one another.
They form one continuous particle with no individual units.
12. Someone opens a container of perfume on one side of a room. After a while, its smell reaches the other side. Which explanation fits the particle model?
Perfume particles remain still while the room moves around them.
Perfume vapor particles move and spread among the air particles.
Air particles pull the perfume in one straight line across the room.
The perfume instantly turns into a solid and spreads across the floor.
13. An ice cube melts inside a tightly sealed container. Assuming nothing enters or leaves, what happens to the total mass of the contents?
It decreases because liquid water is lighter than ice.
It becomes zero while the solid structure disappears.
It increases because liquid particles are closer together.
It stays the same because melting changes state, not the amount of matter.
14. On a very cold morning, frost forms when water vapor changes directly into ice on a surface. What is this change called?
Condensation
Freezing
Sublimation
Deposition
15. Water droplets appear on the outside of a cold glass. Where does this liquid water mainly come from?
Water vapor in the air condensing on the cold surface
Water leaking through tiny openings in the glass
The glass changing into liquid water
Oxygen in the air freezing onto the glass
16. A student pours 100 mL of water from a tall cylinder into a short, wide container without spilling any. What should the student observe?
The water keeps the cylinder's shape but loses volume.
The water has a different shape but still measures about 100 mL.
The water expands to fill every part of the container.
The water becomes a gas because its shape changes.
