Question

What is common between the three states of matter?

Answer 1

Matter:

• It is made up of many particles or atoms.
• Three different states of matter are solid, liquid and gas.

States of matter:

• Solid state: In this state, the molecules are closely packed and cannot move freely from one place to another which means no space between them and the intermolecular force of attraction between the molecules is more.

Example: Ice, Aluminium, sand, etc.

• Liquid state: In this state, the molecules are closely packed but they can move from one place to another which means some space between them and the intermolecular force of attraction are lesser than solid.

Example: water, mercury, blood, etc.

• Gaseous state: In this state, the molecules are not closely packed, and they can move freely from one place to another which means a lot of space between them and the intermolecular force of attraction is very low.

Example: air, steam, Ammonia gas, etc.

Common between three states of matter:

• They are made up of small tiny particles known as atoms/molecules.
• They have a specific mass and can occupy space.
• These three states have volume.
• They have intermolecular spaces of varying magnitude.
• The atoms of these three states have the force of attraction between them, it can be either strong or intermediate, or weak but the intermolecular forces are common in them.
