a pure substance is 1 substance, and has only one kind of atom or molecule.also, only made up of 1 type of matter.

a mixture is made up of many substances, and has 2 or more types of matter.It can also be separated.But, it might not be easy to separate.

All particles of a pure substance are the same. Every water particle, called a molecule, has 2 hydrogen atoms and 1 oxygen atom.

All particles of a mixture are not the same. Salt water solution has some water molecules and some salt that are mixed together.

How does a particle theory explain how a solute dissolves into a solvent?

You can use the particle theory to help explain what happens when solutes dissolve. The particle theory states that there are spaces between all particles. This means that, in a sample of water, there are many water particles, but also many empty spaces. When you look at sugar. The sugar dissolves, the sugar particles separate and mix with the water particles.
