Which answer choice correctly states and describes the relationship between volume and particle motion within the states of matter?

a) they have an indirect relationship, so when the volume for a state of matter increases, its particle motion decreases

b) they do not have any relationship, so they do not affect each other.

c) they have a direct relationship, so when the volume for a state of matter increases, its particle motion increases

d) they have a stable relationship, so the volume and particle motion for state of matter are equal to each other at all times

The correct option is;

c) They have a direct relationship, so when the volume for a state of matter increases, its particle motion increases

Explanation:

The different states of matter are solid liquid and gas

Solids

The most compact form of matter is the solid state where the particles are held closely together and have no little or no motion to each other. The positions of the particles of solid iron are rigidly fixed and a mass of iron does not readily change shape

For example 1 kg of iron has a volume of 127 cm³

Liquids

When the 1 kg of iron is melted the volume it occupies becomes 143.27 cm³

The molten iron particles move freely and takes the shape of the container into which they are placed

Gases

Gases are the lightest state in which matter can exist and they completely fill the container into which they are placed due to their ease of movement.
