Question

Give a reason for the following.

Gases can flow in any direction.

Answer 1

• In gases, molecules are not closely packed with each other.
• They are free to move at will.
• Intermolecular attraction i.e., attractive forces between molecules in gases is negligible.
• Molecules can spread over the entire space available.
• Fluids are substances that can flow.
• Liquid and gas are called fluids since they tend to flow.
• Liquids flow from a higher level to a lower level under the influence of any force generally gravity.
• Gases flow in any direction.
