Questions Related to diffusion in different states of matter

Liquids tend to have better _________ than gases.

chemistry the particle theory diffusion in different states of matter properties of solids, liquid, and gas particle theory of matter

  1. thermal conductivity

  2. compresibility

  3. diffusion

  4. both b and c

Show answer
Correct Option: A
Explanation:

Liquids tend to have better thermal conductivity than gases, and the ability to flow makes a liquid suitable for removing excess heat from mechanical components. 

The limited amount of space between particles means that liquids have _________.

chemistry the particle theory diffusion in different states of matter properties of solids, liquid, and gas particle theory of matter

  1. high compressibility

  2. no compressibility

  3. less compressibility

  4. none of above

Show answer
Correct Option: C
Explanation:

The movement of the particles causes the liquid to be variable in shape. Liquids will flow and fill the lowest portion of a container, taking on the shape of the container but not changing in volume. The limited amount of space between particles means that liquids have only very limited compressibility. 

Which of the following are the characterstics of a liquid?

chemistry the particle theory diffusion in different states of matter properties of solids, liquid, and gas particle theory of matter

  1. It flows, has a fixed volume and an indefinite shape and changes under pressure.

  2. It flows, has a fixed volume and an indefinite shape.

  3. It flows, has a fixed volume and an definite shape.

  4. It flows, has an indetermined volume and an indefinite shape.

Show answer
Correct Option: B
Explanation:

A liquid flows. 


Liquid has a fixed volume, but it does not have a definite shape. 

Liquids take up the shape of the container or vessel in which it is kept and just like solids, liquids too, do not change under pressure because they are generally incompressible. 

Hence, option B is correct.

The property of liquids to resist their flow is called _______.

chemistry the particle theory diffusion in different states of matter properties of solids, liquid, and gas particle theory of matter

  1. rigidity

  2. viscosity

  3. flow

  4. thickness

Show answer
Correct Option: B
Explanation:

The property of liquids to resist their flow is called viscosity.

What are the characteristics of a liquid?

chemistry the particle theory diffusion in different states of matter properties of solids, liquid, and gas particle theory of matter

  1. A state of matter that has a definite volume but not a definite shape.

  2. A state of matter that conducts electricity well.

  3. A state of matter that does not have a definite volume or shape.

  4. A state of matter similar to gas that has free electrons.

  5. A state of matter that has both a fixed volume and shape.

Show answer
Correct Option: A
Explanation:

Liquid state of a matter has a definite volume but not a definite shape because the liquid molecules are bound with weak forces of attraction.


Hence, the correct option is A.

Liquids have a definite volume but an indefinite shape.

chemistry the particle theory diffusion in different states of matter properties of solids, liquid, and gas particle theory of matter

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

Liquids have a definite volume but indefinite shape and size. This is because the intermolecular forces of attraction in liquids are quite weak as compared to the solid states.

Liquids occupy the entire volume of the container in which they are placed.

chemistry the particle theory diffusion in different states of matter properties of solids, liquid, and gas particle theory of matter

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

Liquids do not occupy the entire volume of the container in which they are placed. They occupy only the volume equal to their volume in the container. This is because there is a strong intermolecular force of attraction present between the molecules of the liquid.

The state of matter which has no fixed shape but volume and can freely flow is:

chemistry the particle theory diffusion in different states of matter properties of solids, liquid, and gas particle theory of matter

  1. Gas

  2. Liquid

  3. Solid

  4. None of these

Show answer
Correct Option: B
Explanation:
The state of matter which has no fixed shape but volume and can freely flow is Liquid state.
Hence option B is correct.

The rate of diffusion is higher in liquids than solids because of _____________.

chemistry the particle theory diffusion in different states of matter properties of solids, liquid, and gas particle theory of matter

  1. less inter-molecular space

  2. more force of attraction

  3. high rigidity

  4. high inter-molecular space

Show answer
Correct Option: D
Explanation:

The rate of diffusion is higher in liquids as they have more inter-molecular space so there is more space to diffuse.

Which of the following statements is incorrect?

chemistry matter in our surroundings diffusion in different states of matter properties of solids, liquid, and gas particle theory of matter

  1. Solids generally do not show diffusion

  2. Solids have negligible kinetic energy

  3. Solids cannot be compressed

  4. Solids have indefinite volume

Show answer
Correct Option: D
Explanation:

Any matter that is a solid has a definite shape and a definite volume. The molecules in a solid are in fixed positions and are close together. Although the molecules can still vibrate, they cannot move from one part of the solid to another part. As a result, a solid does not easily change its shape or its volume.
