Matter can be classified into three states - solids, liquids, and gases. Solids have a definite shape and volume, while liquids have a definite volume but no definite shape. Gases have neither a definite shape nor volume. The key differences between the three states are the arrangement and movement of their particles - solid particles are closely packed, liquid particles are less closely packed, and gas particles are loosely arranged and flow freely in all directions.

3.  Solids – They have a definite shape and
a definite volume
 Liquids – They do not have a definite
shape but have a definite volume
 Gases - They have neither a definite
shape nor a definite volume

space
Negligible as the
molecules are closely
packed
Have more intermolecular
