Question

Which of the following does not change its shape ( ) A) Solid B) Liquid C) Gas D) none of these​

Answer 1

Option A) Solid does not change its shape.

• The arrangement of atoms in a solid is close and compact. The atoms cannot move or travel from one place to another.
• This is the reason why solids are rigid and cannot change shape.
• The arrangement of atoms in liquids is loosely packed. Therefore they can take the shape of the container in which they are put.
• In gases, the atoms are very loosely packed. They can disperse very quickly because they are not bonded to each other strongly.

Answer 2

Answer:

Solids cannot change their shape.

Explanation:

Basically, the matter exists in three forms Solids, Liquids, Gases.

Characteristics:

Solids: They have fixed shape and volume.

They cannot be compressed.

In solids, the space between the particles is negligible.

High density.

Liquids: They have a fixed volume but no fixed shape.  

They can be compressed.

The space in between the particles is considerable.

The density is less than solids.

Gases: Neither fixed shape nor volume.

Gases can be compressed.

The particles are very spacially arranged.

They have the least density.

Therefore, solids cannot change their shape.
