Question

what are the three states of matter and explain it detaily ?​

Answer 1

The three states of matter are: solids, liquids and gases.

• Solids- A solid has a definite shape and definite volume.

Example - wood, stone, iron, Ice etc.

• Liquid - A liquid has a definite volume but not definite shape.

Example - water, Juice, milk, oil, etc.

• Gases - A gas neither has definite shape nor a definite volume.

Example - air. hydrogen, oxygen. water vapour etc

Three states of Matter are:-

1. Solid
2. Liquid
3. Gas

Solids

• The solid state is one of the fundamental states of matter.
• Solids differ from liquids and gases by the characteristic of rigidity.
• The molecules of solids are tightly packed because of strong intermolecular forces; they only oscillate about their mean positions..
• Solids can be defined as the state of matter which has definite shape and volume and has a rigid structure.
• Solids possess the least compressibility and thermal expansion.

Example: Iron (Fe)

Liquids

• The molecules in a liquid are closely packed due to weak intermolecular forces.
• These forces are weaker than solids but stronger than that of gases.
• There is much space in between the molecules of liquids which makes their flowing ability easy.
• Liquids can easily acquire the shape of a vessel, and they have a fixed volume.
• Conversion of solids into liquids takes place when we increase the temperature of solids to a point where solids begin to melt.
• Generally, the density of liquid lies between the density of solids and gases. Compressibility and thermal expansion of liquids are slightly higher than that of solids.

Example: Water (H2O)

Gases

• In this state of matter, distances between the molecules are large (intermolecular distance is in the range of
• The intermolecular forces experienced between them are negligible.
• Thus, translatory, rotatory and vibratory motions are observed prominently in gases.
• Gases do not have any fixed shape or volume.
• They also possess high compressibility and thermal expansion.

Example: Oxygen (O2)
