Question

Which state of matter has the highest density and why

Answer 1

solid state has the highest density because the atoms inside the solid are very closely packed

Answer 2

Among the three states of matter solids have the highest density because strong attractive forces keep the molecules of the solid close and tightly packed where as we know liquids and gases have a tendency to flow, because of presence of intramolecular spaces and random movement of molecules but this is not the case with solids.

Solid is of highest density due to its close packing of molecules inside a substance there is no space between the molecules and they are closely and linearly arranged inside the given surface.
