Question 1
1 / -0

Which of the following statements is false regarding properties of solids and liquids?

A
Both occupy space

B
Both have definite shape

C
Both have definite volume

D
Both are visible with naked eye

Solution

Solids (mostly) have definite shape but liquids do not have definite shape. Liquids take the shape of the container in which they are kept. Hence, the statement contained in alternative B is false regarding properties of solids and liquids.

The correct answer is B.
Question 2
1 / -0

When water is in the liquid form, its molecules

A
are closely packed in a fixed position

B
are loosely connected to one another

C
are free to move independently

D
vibrate about a fixed position

Solution

The molecules are closely packed in solids, followed by liquids and then gases.

Hence, the correct answer is option B.
Question 3
1 / -0

Which alternative does not differentiate solids from gases?

A

Solids Gases

Definite shape No definite shape

B

Solids Gases

Fixed volume No fixed volume

C

Solids Gases

Low density High density

D

Solids Gases

Cannot flow Can flow

Solution

The intermolecular force of attraction is very strong in solids and because of this the constituting particles in solids are very closely packed.

The intermolecular force of attraction is very weak in gases and because of this the constituting particles are present far away from each other.

Thus, the density of a solid is usually higher than that of a liquid or a gas.

The correct answer is C.
Question 4
1 / -0

Which of the following substances has a fixed shape and a fixed volume?

A
Milk

B
Stone

C
Water vapor

D
Carbon dioxide

Solution

The intermolecular force of attraction is very strong in solids and because of this the constituting particles in solids are very closely packed. Hence, they have a fixed shape and a fixed volume. Among the given substances, only stone is a solid. Hence, stone has a fixed shape and a fixed volume.

The correct answer is B.

Question 5

1 / -0

Use the following information to answer the next question.

The three states of matter are labeled as I, II, and III in the given table.
I	Definite shape, size, and volume
II	No fixed shape or volume
III	Definite volume but no shape

Which alternative correctly classifies I, II, and III?

I II III

Gas Liquid Solid

I II III

Gas Solid Liquid

I II III

Solid Gas Liquid

I II III

Solid Liquid Gas

Solution

The intermolecular force of attraction is very strong in solids and very weak in gases. In liquids, the intermolecular force of attraction is fairly strong.

The constituting particles in solids are very closely packed. Hence, solids have a definite shape and size. Thus, solids are labeled as I.

The constituting particles in liquids are loosely packed. Hence, they cannot retain their shape. However, the intermolecular force of attraction in a liquid is strong enough to keep its volume intact. Thus, gases are labeled as II.

The constituting particles in gases are spread out. The force holding the gaseous particles is very weak. Hence, gases neither have a definite shape nor a definite volume. Thus, liquids are labeled as III.

The correct answer is C.

Question 6

1 / -0

Use the following information to answer the next question.

The given table classifies substances according to their intermolecular force of attraction.
Substance	Intermolecular force of attraction
Stone	I
Oxygen	II

Which alternative correctly completes the given table?

I II

Strong Strong

I II

Strong Weak

I II

Weak Strong

I II

Weak Weak

Solution

Stone is a solid substance, whereas oxygen exists as a gas. The intermolecular force of attraction is very strong in solids and very weak in gases.

The correct answer is B.

Question 7
1 / -0

Which of the following changes does not take place when a solid is converted to a liquid?

A
Atoms/molecules gain energy

B
The distance between the atoms/molecules increases

C
Forces that hold the atoms/molecules increase in magnitude

D
Atoms/molecules that comprise the substance vibrate faster in liquids

Solution

When a solid melts to form a liquid, the forces that hold the particles together becomes weak. Therefore, the distance between particles increases.

The correct answer is C.

Question 8

1 / -0

Use the following information to answer the next question.

When a liquid is transferred from a round container to a cubical container, the liquid takes the shape of the latter. However, when a piece of wood is transferred from a round container to a cubical container, its shape remains the same.

Which of the following conclusions drawn from the given observation is incorrect?

Unlike solids, liquids take the shape of the container they are put in

Liquids can flow easily and solids do not flow at all

Unlike solids, liquids have a definite shape

Liquids and solids have a fixed volume

Solution

The intermolecular force of attraction is very strong in solids. In liquids, the intermolecular force is quite weak. Therefore, the constituting particles in solids are very closely packed, while those in liquids are loosely packed. Hence, solids have a definite shape but liquids do not.

The correct answer is C.
