Question

Quizplus · Accepted Answer

Solids are generally the densest state of matter of any given substance. This is because the molecules in a solid do not have enough kinetic energy to move around. 
Liquids and gasses each have enough kinetic energy to move apart from each other, which reduces their density compared to a solid.
