Homogeneous Mixture Definition: Lesson for Kids Pure alcohol could be ethanol, methanol, or a mixture of different alcohols, but as soon as you add water (which is not an alcohol), you no longer have a pure substance. It cannot be separated into components without breaking chemical bonds. In contrast, when water vapor is adsorbed, the water molecules remain on the surface of the material. Hygroscopic and deliquescent materials and humectants are all able to absorb moisture from the air. A sample of silicon consists of only one type of atom: silicon atoms.
