Questions Related to particle theory of matter

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

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

  1. high compressibility

  2. no compressibility

  3. less compressibility

  4. none of above
Reveal answer Fill a bubble to check yourself
C Correct answer
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?

  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.

B Correct answer
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.

What are the characteristics of a liquid?

  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.

A Correct answer
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 occupy the entire volume of the container in which they are placed.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
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 rate of diffusion is higher in liquids than solids because of _____________.

  1. less inter-molecular space

  2. more force of attraction

  3. high rigidity

  4. high inter-molecular space
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

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

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

Which of the following statements is incorrect?

  1. Solids generally do not show diffusion

  2. Solids have negligible kinetic energy

  3. Solids cannot be compressed

  4. Solids have indefinite volume
Reveal answer Fill a bubble to check yourself
D Correct answer
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.
