Question

State three charactersitics of molecules of matter
which determine its solid, liquid and gaseous state.​

Answer 1

★ l l MATTER l l ★

Anything which occupies space and has mass is called Matter.

On basis of physical properties, matter is classified as:

1. Solids
2. Liquids
3. Gases

Characteristics of solids:

• Solid have fixed shape and volume.

• Solids are incompressible.

• Solids have high densities.

• Solids cannot flow.

• Solids are highly rigid.

• Solids don't fill their containers completely.

Characteristics of Liquid:

• Liquids have a fixed volume but no fixed shape.

• Liquids cannot be compressed much.

• Liquids have moderate to high density.

• Liquids can flow easily.

• Liquids don't fill their container completely.

Characteristics of Gases:

• Gases have neither fixed shape nor a fixed volume.

• Gases can be compressed easily.

• Gases have low densities.

• Gases can fill their container completely.

• Gases flow easily.
