Question

What is matter? Explain the three states of matter on the basis of the particular nature of matter

Answer 1

Matter:

• The matter is defined as everything that fills space and has mass.
• Air and water, sand and sugar, hydrogen and oxygen, and so on.
• The matter is made up of extremely small, microscopic particles.
• Because matter particles have space between them, they attract one another.
• Example: Book, pen, glass, etc.

Matter can be divided into three states based on the nature of particles.

1. Solid-state: In this state, the particles are tightly packed due to high intermolecular force of attraction thus, resulting in the least intermolecular space.
2. LIquid state: In this state, the particles are loosely packed due to a lower intermolecular force of attraction, when compared to solids, resulting in a greater intermolecular space.
3. Gaseous state: In this state, the particles are more loosely packed due to the lowest intermolecular force of attraction, when compared to solids and liquids, resulting in the largest intermolecular space.
