Question

Intermolecular spaces are minimum in the case of:

• A. Solids
• B. Liquids
• C. Gases
• D. Plasma

Answer 1

The correct option is A

Solids

Explanation for the correct option:

Option(A) Solids

• Solids have definite shape and definite volume due to strong inter-molecular forces of attraction.
• Solids show tight molecular arrangement due to which there is negligible inter-atomic movements.
• Hence, they show the least inter-molecular spaces.

Explanation for the incorrect options:

• Liquids are fluids that show intermediary properties between solids & gases. They have less intermolecular forces of attraction with respect to solids. So, they have relatively more intermolecular spaces than solids but less than gases.
• Gases are fluids that have the least intermolecular forces of attraction hence, they have highest intermolecular spaces and can move freely occupying the entire free space they get to fill in.
• Plasma is that state of matter where we get to see the breaking of gaseous particles into its ionic form i.e. negative & positive charges with the application of extremely high temperatures.

Therefore, option (A) is correct. Intermolecular spaces are minimum in case of solids.
