Which of the following has the highest density?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Solid.
solid, liquid, gas, and plasma—solids generally have the highest density. Density is defined as mass per unit volume (ρ = mass/volume), and in solids, particles are tightly packed in an orderly manner, resulting in a higher mass within a smaller volume. Liquids have particles that are less tightly packed, and gases have particles that are widely spaced, giving them the lowest density.
Other Options:
Liquid – Particles are loosely packed compared to solids, so they have lower density than most solids.
Plasma – An ionized gas with very low particle density, commonly found in stars; it’s less dense than solids.
Gas – Gases have particles spread far apart, resulting in the lowest density among the four states of matter.
