Which of the following has the highest density?

Correct option is C

The correct answer is (c) Solid

• Density is defined as mass per unit volume, and it typically varies across different states of matter.

• Solids have the highest density because their particles are closely packed together, leaving very little space between them. This tight packing results in a high mass per unit volume.​

Information Booster:

• Density is a fundamental property of matter that differs significantly between states: solids, liquids, and gases.

• Solids have the most tightly packed structure, giving them the highest density (e.g., lead, steel).

• Liquids are denser than gases but less dense than solids (e.g., water, oil).

• Gases have the least density due to their loose structure (e.g., air, helium).

• Plasma, while being the fourth state of matter, has low density compared to solids because the particles in plasma are widely spaced.

Additional Information:

• Liquid: Liquids are more dense than gases but less dense than solids. For example, water is denser than air but less dense than solid metals.

• Plasma: Plasma, found in stars and lightning, has charged particles but remains less dense than solid matter due to particle separation.

• Gas: Gases, like oxygen and nitrogen, have a very low density because of the significant space between molecules.
