Shaun and sara are studying the states of matter together in science class. their teacher asks them to list the states of matter and determine in which state the particles move freely. which statement is correct?
a. there are two states of matter, and particles move freely in the liquids states.
b. there are three states of matter, and particles move freely in the gaseous state.
c. there are four states of matter, and particles move freely in their solid state.
d. there are five states of matter, and particles move freely in both their solid and gaseous states.

The B statement is correct. There are three states of matter, and particles move freely in the gaseous state.

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.
