Play an AI-generated podcast conversation about this lesson

Why are gases highly compressible as compared to solids and liquids?

Gases have a fixed shape and volume.

Solids and liquids have particles that are not in constant motion.

Gases have particles that are far apart with large spaces between them. (correct)

Solids and liquids have particles that move very quickly.

Which application demonstrates the use of compressed gas for household purposes?

Using liquefied petroleum gas (LPG) in cooking cylinders at home. (correct)

Transporting gases in large volumes inside small cylinders.

Supplying oxygen to hospitals in compressed cylinders.

Using compressed natural gas (CNG) in vehicles as fuel.

Why does the smell of food diffuse quickly in the air compared to solids and liquids?

The aroma particles of food mix easily with particles of air due to high gas compressibility.

The particles of gases move randomly at high speeds and spread faster. (correct)

Gases have a lower speed of diffusion compared to solids and liquids.

Solids and liquids form stronger bonds, hindering their diffusion rate.
