Gases
Solids
The state of matter with the lowest density is gas. Gases have molecules that are far apart and are free to move around in any direction, resulting in a low density compared to liquids and solids.
The density of solids is generally higher compared to liquids and gases because the particles in solids are more closely packed together. Liquids have a higher density than gases due to their closer particle arrangement, but lower density than solids. Gases have the lowest density as their particles are the most spread out and have the most kinetic energy.
The kinetic energy is lowest in solids, higher in liquids, and highest in gases.
no
because of density
in relation to solids or liquids in liquids: Density. A lighter density compound/liquid will float in a heavier density liquid
Not all liquids have lower densities than all solids. Low density solids frequently contain air or other gasses as part of their makeup (cok, Styrofoam, etc)
In general, the solid state has the highest density due to the closely packed arrangement of particles. Liquids have a lower density compared to solids because particles are more spread out. Gases have the lowest density as their particles are far apart and can move freely.
Not all liquids have lower densities than all solids. Low density solids frequently contain air or other gasses as part of their makeup (cok, Styrofoam, etc)
particle density
Generally, the density of solids, liquids, and gases decreases as they are heated. When heated, the particles in these substances gain energy and move more, causing the substance to expand, which leads to a decrease in density.
