Question 1
1 / -0

Which of the following statements is incorrect about the nature and characteristics of matter?

A
Matter is made up of particles which are very small in size.

B
Particles of matter have spaces between them.

C
Particles of matter are static, but they start moving on heating.

D
Matter is held together by means of a force of attraction between its particles.

Solution

Particles of matter are continuously moving. They possess kinetic energy, and are in a continuous motion. On heating, the kinetic energy of the particles increases, which makes them move faster.
Question 2
1 / -0

Which of the following substances has a definite volume and can take the shape of the container in which it is poured?

A
Stone

B
Brick

C
Coconut oil

D
Water vapour

Solution

Coconut oil is a liquid. Its constituting particles are loosely packed as compared to the constituting particles in solids. Thus, coconut oil has a definite volume, but it takes the shape of the container in which it is poured.
Question 3
1 / -0

By applying pressure and reducing the temperature

A
liquids can be converted into gases

B
solids can directly be converted into gases

C
gases can directly be converted into solids

D
solids can be converted into liquids

Solution

Volume of a substance decreases when its temperature is decreased or pressure is applied on it. When pressure is applied on gas and its temperature is decreased simultaneously, it changes into solid state directly.
Question 4
1 / -0

In which of the following substances is the speed of molecules the highest?

A
Ice

B
Kerosene

C
Sugar cube

D
Water vapor

Solution

As the thermal energy is added to a solid it changes to a liquid and then to a gas.

Among the given substances only water vapor is present in gaseous state. Hence, speed of molecules will be the maximum in the water vapor.
Question 5
1 / -0

Use the following information to answer the below question.

Martha mixed some marble powder with dry ice. On keeping the mixture in the open air for a few minutes, the dry ice vanished and only the dry powder was left behind.

The dry ice vanished because of

A
evaporation

B
sublimation

C
condensation

D
freezing

Solution

The dry ice gets directly converted from the solid-state to the gaseous state, without passing through the liquid state. This process is known as sublimation.
Question 6
1 / -0

Which of the following statements about diffusion of matter is correct?

A
The rate of diffusion of gases is more than that of liquids and solids.

B
The rate of diffusion of liquids is more than that of gases and solids.

C
The rate of diffusion of gases is more than that of liquids, but less than that of solids.

D
The rate of diffusion of liquids is more than that of gases, but less than that of solids.

Solution

The intermixing of particles of two different types of matter on their own is called diffusion. The rate of diffusion of matter is in the following order:

Rate of diffusion of gas > Rate of diffusion of liquid > Rate of diffusion of solid
Question 7
1 / -0

Which of the following statements about the properties of solids is false?

A
Their density is more than that of gases.

B
They are less compressible than gases.

C
They have a definite shape and size.

D
Their particles are loosely packed.

Solution

The constituent particles of solids are closely packed. The constituent particles of gases are loosely packed.

The correct answer is D.

Why alternatives A, B and C are wrong:

Solids are substances having a definite shape and size. They are less compressible and denser than gases.
Question 8
1 / -0

Use the following information to answer the next question.

Martha listed the properties of liquids and gases as follows:

(I) Both occupy space

(II) Both have indefinite volume

(III) Both have definite shape

(IV) Both can be poured from one container to another

Among the given properties, Martha listed two properties incorrectly.

The properties listed incorrectly by Martha are

A
I and II

B
II and III

C
II and IV

D
III and IV

Solution

Both liquids and gases have indefinite shape but liquids have definite volumes. Gases have volume but it is not definite. Gases expand to the complete volume of the vessel they are contained in. Thus, gases cannot be poured from one container to another like liquids.

The correct answer is D.

Why alternatives A, B and D are wrong:

Both liquids and gases have an indefinite shape and take the shape of the container in which they are present. Both liquids and gases have volume. Thus, they both occupy space. The properties I and III are correctly listed and II and IV are incorrectly listed by Martha.
Question 9
1 / -0

Which process is involved in the drying of clothes?

A
Evaporation

B
Condensation

C
Fusion

D
Sublimation

Solution

In the process of drying of clothes, water present in liquid state in the clothes changes into water vapour and leaves the clothes. The process in which a liquid changes to its gaseous state below its boiling point is known as evaporation. Thus, evaporation is involved in the process of drying of clothes.
Question 10
1 / -0

The correct order of increasing compressibility of matter is

A
Oxygen < Wood < Alcohol

B
Wood < Alcohol < Oxygen

C
Alcohol < Oxygen < Wood

D
Oxygen < Alcohol < Wood

Solution

Particles of matter have space between them. However, there is variation in space for different matters. The particles of gas have the maximum space between them. Therefore, gases have the highest compressibility among solids, liquids, and gases. The particles of solids have the minimum space between them. Therefore, solids have the lowest compressibility among solids, liquids, and gases.

The compressibility of liquids is intermediate between solids and gases. Oxygen is a gas, alcohol is a liquid, and wood is a solid. Hence, the correct order of increasing compressibility is Wood < Alcohol < Oxygen
