"sequence the kinetic energy, temperature, and density of most solids, liquids, and gases. use 1 to represent the lowest amount and 3 to represent the highest."

Kinetic energy

Solids 1, liquids 2, gases 3

Temperature

Solids 1, liquids 2, gases 3

Density

Solids 3, liquids 2, gases 1

Explanation:

Most of elements can be in the three different states at different temperatures, solid in lower temperatures then liquid and gas in higher temperatures.

When it's gaseous it is more expanded, it's volume is bigger then it's density is lower. As the molecules are more separated they can move more easily.

On the opposite hand in solid state, it's more compressed, the volume is smaller and the density is higher. The molecules are more compressed an they can't move easily.
