Matter in Our Surroundings -online MCQ test 1

Question 1: What is the matter?

A) anything that has mass.

B) anything that has volume.

C) anything that has mass and volume.

D) none

Explanation: Matter is a substance made up of various types of particles that occupies physical space and has mass.

Question 2: The matter is made up of:

A) cells

B) molecules

C) gas

D) Particles

Explanation: Matters(Solids, liquids, and gases) are made of tiny particles called atoms and molecules.

Question 3: Particles of matter have:

A) spaces between them

B) volume

C) potential energy

D) none

Explanation: All matter is made up of particles called atoms and molecules,the space between them is called intermolecular space.

Question 4: Particles of the matter:

A) attract each other

B) repel each other

C) both of them

D) none of them

Explanation:Solids, liquids, and gases are made of tiny particles called atoms and molecules. In a solid, the particles are very attracted to each other.

Question 5: Matter exists in :

A) one

B) two

C) three

D) five

Explanation: There are five known phases, or states, of matter: solids, liquids, gases, plasma and Bose-Einstein condensates.

Question 6: liquids are :

A) compressible

B) not compressible

C) light

D) all of them

Explanation: Liquids have molecules which can move freely. But the forces that keep these molecules together are strong. So liquids are not compressible.

Question 7: gases are:

A) compressible

B) not compressible

C) highly compressible

D) none

Explanation: Gases are highly compressible because they have large intermolecular spaces between the molecules.

Question 8: The density of gases is:

A) maximum

B) minimum

C) medium

D) none

Explanation: Gas is much less dense than solids and liquids.

Question 9: The states of matter are

A) interchangeable

B) interconvertible

C) interlinked

D) none

Explanation: The three natural states of matter are interconvertible. This means that you can turn a solid into a liquid, or a liquid into gas, and vice versa.

Question 10: The factor responsible for converting one state of matter into another:

A) change in temperature

B) change in pressure

C) change in humidity

D) both A and B

Explanation: Temperature and pressure are the two factors which can change the physical state of matter,When thermal energy is added to a substance, its temperature increases which can change its state from solid to liquid, liquid to gas or solid to gas.The increase in pressure changes the state of matter from gas to liquid and also from liquid to solid.
