The particles of solids are usually arranged in an order manner or pattern based on their crystal lattices. Solid particles are tightly and closely packed together and are held by a very strong attractive force.
Liquids do not have a fixed shape. Liquids have a definite volume which can easily be determined. The particles of liquids are closely packed and held by a stronger attractive force than those of gases but less strong when compared solids.
