States of Matter Questions

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

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. 

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

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.

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 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.

Liquids and gases ....................... on heating.

  1. contract

  2. expand

  3. melt

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

Liquids and gases expand when they are heated. This is because the particles in liquids and gases move faster when they are heated than they do when they are cold. As a result, the particles take up more volume. This is because the gap between particles widens, while the particles themselves stay the same size.

Look at the classification table below. Which of the following sets of headings is correct?

I II III
Oil Snow Wind
Paint Crayon Oxygen

  1. (I) Gas (II) Liquid (III) Solid

  2. (I) Liquid (II) Gas (III) Solid

  3. (I) Liquid (II) Solid (III) Gas

  4. (I) Solid (II) Gas (III) Liquid
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Oil and paint exist in the liquid state, crayon and snow are in the solid-state while wind and oxygen exist in the gaseous state. Hence, I - liquid, II - solid and III - gas.

Hence, the correct option is $C$.

Mechanical work is specially important in systems that contains :

  1. gas-liquid

  2. liquid-liquid

  3. solid-solid

  4. amalgam
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Mechanical work is important in systems that undergo appreciable change in volume. 


Since solids are incompressible, hence mechanical work is insignificant in solids. 

However, gases and liquids(to some extent) undergo appreciable change in volume and hence, mechanical work becomes important in case of gases and liquids.

Therefore, the option is A.
