Question

Which of these object will have maximum intermolecular spaces.

• A. Rock
• B. Milk
• C. Steam
• D. Water

Answer 1

The correct option is C

Steam

Explanation for correct option.

C)-Steam

Steam is a gaseous substance.

• Gases are substances that neither has a definite shape nor volume.
• In gases, molecules are loosely packed.
• The intermolecular force of attraction in gases is very weak, almost negligible.
• Thus the molecules can move freely.
• The intermolecular spaces are maximum in gas.
• Gases can easily flow in all directions. They can be compressed easily.

Explanation for incorrect options.

(A)-Rock

• Rock is a solid substance.
• Solids are a substance that has a definite shape and volume.
• In solids, molecules are tightly packed together and intermolecular forces are very strong.
• They have negligible intermolecular spaces.
• They cannot flow, solids are rigid and incompressible.

(B)-Milk,(D)-Water

• Both are liquids, liquids are substances that do not have a definite shape, but have a definite volume.
• In liquids molecules are less tightly packed and have weak intermolecular forces.
• The molecules in a liquid have greater intermolecular space than solid but less than that of gases.
• The liquids have a definite volume. They take the shape where they are contained.
• Liquids can flow and can be compressed to a small extent.

There for the option(C) is the correct answer.
