We are asked to compare the different states of matter. We have three: solid, gaseous, or liquid.
There are many differences between each state, first there is the visual part. At a glance we can define whether an element is in solid, liquid, or gaseous form. Its state is directly related to the arrangement of the molecules.
Solid: The molecules are very close together, it has a defined structure.
Liquid: The molecules are a little separated, they move a little more freely and their shape adopts the container in which they are contained.
Gas: There is a lot of space between the molecules, they move freely and there is almost no interaction between the molecules.
