Matter & Mixtures: Matter and Types of Mixtures (1 of 4) |
Matter has mass and takes up (occupies) space. Mixtures are made of different substances (elements or compounds) that are together but not chemically bonded. Mixtures can be separated by physical means (filtering, picking stuff out, evaporating liquid, etc.). Homogenous mixtures are the same throughout (e.g. salt water, milk, jello, etc.). Heterogeneous mixtures are not the same throughout (a salad, rocks in water, etc.). Think of them as "chunky". Pure substances are not mixtures. A pure substance is made up of only one substance. |
