Question

_______ have neither fixed shape nor fixed volume.

Answer 1

• Matters normally exist in three states viz. solid, liquid and gas.

Solids-

• Solids are characterized by definite shape and definite volume.
• A solid can be rigid or flexible, hard or soft, compressible or non-compressible, and light or heavy.
• A wooden block and a piece of chalk are the two examples of solids.

Liquids-

• Liquids are characterized by definite volume.
• They do not have their own definite shape and can be shaped according to the vessel they are placed in.
• Water and Milk are the two examples of liquids.

Gases-

• Gases do not have any definite shape or a definite volume.
• Gases cannot be confined to an open container.
• Oxygen(O₂) and Carbon dioxide(CO₂) are the two examples of gases.

Hence, Gases have neither a fixed shape nor fixed volume.
