What are the three states of matter?

Detailed Solution for Test: States Of Matter - Question 1
The three primary states of matter are solid, liquid, and gas. Solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases have neither a definite shape nor volume.
Test: States Of Matter - Question 2

Which of the following can change its shape under force?

Detailed Solution for Test: States Of Matter - Question 3
A rubber band is flexible and can change its shape when a force is applied, unlike rigid materials like wood or stone.
Test: States Of Matter - Question 4
Save
What happens when a sponge is compressed?
Detailed Solution for Test: States Of Matter - Question 4
When a sponge is compressed, the air trapped inside it is forced out, reducing its volume.
Test: States Of Matter - Question 5

Which state of matter has particles that move freely and has maximum space between them?
Detailed Solution for Test: States Of Matter - Question 5

The correct answer is C: Gas.
- Particle Movement: In a gas, particles move freely and rapidly in all directions.
- Particle Spacing: Gases have the maximum space between particles compared to solids and liquids.
- Kinetic Energy: Gas particles have higher kinetic energy, causing them to overcome attractive forces easily.
- Shape and Volume: Gases do not have a fixed shape or volume; they expand to fill their container.
- Diffusion: Due to the large spaces, gases diffuse quickly, mixing with other gases.

Test: States Of Matter - Question 6
Save
Liquids can change their shape because:
Detailed Solution for Test: States Of Matter - Question 6
The particles in liquids can move past each other, which allows liquids to change their shape depending on the container they are in.
Test: States Of Matter - Question 7
Save

Which of the following can diffuse in water?
Detailed Solution for Test: States Of Matter - Question 7

- Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration.
- In water, both liquids and gases can diffuse:
- Liquids: When mixed with water, they spread out evenly through the process of diffusion.
- Gases: Dissolve in water and spread out due to the random movement of molecules.
- Solids typically do not diffuse unless they first dissolve in water.
- Therefore, the correct answer is D: Liquids and gases.

Test: States Of Matter - Question 8
Save
Which of the following is highly compressible?
Detailed Solution for Test: States Of Matter - Question 8
Gases are highly compressible because their particles are spread far apart and can be pushed closer together under pressure.
Test: States Of Matter - Question 9
Save
Why does the smell of food reach us in seconds?
Detailed Solution for Test: States Of Matter - Question 9
In gases, particles move quickly and can spread over long distances, allowing the smell of food to reach us rapidly.
Test: States Of Matter - Question 10
Save
What is the main reason gases exert pressure on the walls of their container?
Detailed Solution for Test: States Of Matter - Question 10
Gas particles move randomly and collide with the walls of their container, exerting pressure.
Test: States Of Matter - Question 11
Save
The state of matter in which particles move randomly at high speed is:
Detailed Solution for Test: States Of Matter - Question 11
In gases, particles move randomly and at high speeds, which allows them to spread out and fill any container.
Test: States Of Matter - Question 12
Save
What is the melting point of ice?
Detailed Solution for Test: States Of Matter - Question 12
The melting point of ice is 0°C or 273.15 K, the temperature at which solid ice turns into liquid water.
Test: States Of Matter - Question 13
Save
What is the latent heat of fusion?
Detailed Solution for Test: States Of Matter - Question 13
The latent heat of fusion is the amount of heat energy required to change a solid into a liquid at its melting point, without changing its temperature.
Test: States Of Matter - Question 14
Save
Which of the following statements is true for boiling?
Detailed Solution for Test: States Of Matter - Question 14
Boiling involves the entire liquid gaining enough energy for particles to escape into the gas phase, unlike evaporation which happens only at the surface.
Test: States Of Matter - Question 15
Save
The temperature at which a liquid starts boiling is called its:
Detailed Solution for Test: States Of Matter - Question 15
The boiling point is the temperature at which a liquid changes to a gas (vaporizes) throughout the entire liquid.
Test: States Of Matter - Question 16
Save
Which of the following is true about the latent heat of vaporization?
Detailed Solution for Test: States Of Matter - Question 16
The latent heat of vaporization is the amount of heat energy needed to convert a liquid into a gas without changing its temperature.
Test: States Of Matter - Question 17
Save
Why does ice float on water despite having a lower density than water?
Detailed Solution for Test: States Of Matter - Question 17
Ice is less dense than liquid water because its molecular structure creates gaps that trap air, making it float.
Test: States Of Matter - Question 18
Save
Which state of matter has particles tightly packed in fixed positions?
Detailed Solution for Test: States Of Matter - Question 18
In solids, particles are closely packed in a fixed arrangement, giving solids a definite shape and volume.
Test: States Of Matter - Question 19
Save
What happens when the temperature of a solid is increased?
Detailed Solution for Test: States Of Matter - Question 19
As the temperature increases, the particles in a solid vibrate faster, which may eventually lead to a phase change (e.g., melting).
Test: States Of Matter - Question 20
Save
Which of the following substances can be found in all three states of matter?
Detailed Solution for Test: States Of Matter - Question 20
Water can exist in all three states: solid (ice), liquid (water), and gas (steam), depending on the temperature and pressure.
