Question

Identify the error in the given statement. Circle the incorrect word and write the correct word in the blank.

Gases are rigid and hard.

Answer 1

• A gas neither has a definite shape nor a definite volume.
• We cannot see gases but they are everywhere around us.
• We feel the air around us which is a mixture of many gases like oxygen, carbon dioxide, nitrogen, and others.
• Gases are highly compressible. Since molecules remain far apart due to weak intermolecular forces, these molecules can be brought closer by applying pressure. That is, gases can be compressed.
