Question

In gases, particles vibrate:

• A. about their mean position
• B. about a vertical axis
• C. about a horizontal axis
• D. in any direction

Answer 1

The correct option is D in any direction

Gases are everywhere. You may have heard about the atmosphere. The atmosphere is an envelope of gases that surrounds the Earth. In solids, atoms and molecules are compact and close together. Liquids have atoms that are spread out a little more. The molecules in gases are really spread out, full of energy and constantly moving around in random ways.

So, in gases, molecules vibrate in all directions.
