It is important to understand the particle nature of matter. ... The particles that make up matter are not 'small bits of solid' or 'small drops of liquid' but atoms and molecules. The physical characteristics of those atoms and molecules decide its state.

Answer:
Matter can exist in one of three main states: solid, liquid, or gas. Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around. ... Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume.
EXAMPLE:
At ordinary temperatures, for instance, gold is a solid, water is a liquid, and nitrogen is a gas, as defined by certain characteristics: solids hold their shape, liquids take on the shape of the container that holds them, and gases fill an entire container. These states can be further categorized into subgroups.
