Answer:
The B statement is correct. There are three states of matter, and particles move freely in the gaseous state.
Step-by-step explanation:
State of matter can be described as the different forms in which matter can subsist. Mainly, there are three forms of matter i.e solid, liquid and gases.
Solids are the state of matter in which particles are tightly packed. Due to being tightly packed, the particles in a solid cannot move hence solids have definite shape and volume.
If a solid is heated above it's melting point, it turns into a liquid. The particles in a liquid are not as closely packed as in solids. hence, shape of liquids is not definite.
Gases can be described as state of matter in which particles are free to move. Gases do not have a definite shape or volume.
