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

Liquids are usually difficult to_____________.

  1. hold in a container

  2. compress

  3. change state

  4. apply pressure
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Liquids are found between the solid and gas states. A trait of liquids is that they are difficult to compress.


 When you compress something, you take a certain amount of material and force it into a smaller space or volume. You force the atoms closer together.

 Liquids tend to be difficult to compress because the molecules are already close together.

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

The rate of diffusion of liquids is __________.

  1. higher than gases

  2. lower than solids

  3. higher than solids

  4. equal to gases
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The rate of diffusion of liquids is higher than that of solids. This is due to the fact that in the liquid state, particles move freely and have greater space between each other as compared to particles in the solid state.

________ can usually be reduced by heating the liquid.

  1. Pressure

  2. Temprature

  3. Latent heat

  4. Viscosity
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Viscosity is a measure of how much a liquid resists flowing freely. Viscosity can usually be reduced by heating the liquid. When heated, the particles of the liquid move faster, allowing the liquid to flow more easily.

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

Volatile liquids have ___________.

  1. low viscosity

  2. high boiling point

  3. low boiling point

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

Volatile liquids have low boiling point. As a result, they evaporate very easily at room temperature. Because of their low boiling points, volatile liquids convert to the gas phase at a lower temperature and the gas molecules can diffuse faster than the molecules of a non-volatile liquid.

Liquid and solid are both termed as ________ , while liquid and gases are termed as ___________ .

  1. condensed, fluids

  2. fluids, condensed

  3. condensed, gaseous liquid

  4. none of above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The density of a liquid is usually close to that of a solid, and much higher than in a gas. Therefore, liquid and solid are both termed condensed matter. On the other hand, as liquids and gases share the ability to flow, they are both called fluids. 

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.
Reveal answer Fill a bubble to check yourself
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.
Reveal answer Fill a bubble to check yourself
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.

Which of the following is not the state of matter?

  1. Solid

  2. Liquid

  3. Gas

  4. Vapour
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Matter has three main state of matter that is solid, liquid and gas. Vapour is the type of substance which forms when liquid converts into the gaseous phase. It is a matter but not a state of matter.

Which of the following states of matter exerts pressure on the walls of the container?

  1. Solids

  2. Liquids

  3. Gases

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Among all the states of matter, gases exert pressure in all directions. Liquids and solids exert pressure along the gravity (generally).


Because of negligible force of attraction between particles of gas, the particles of gas have the highest kinetic energy.
