Matter can be classified in many ways: State/phase - solid (rigid shape, fixed volume), liquid (fixed volume but fluid; take the shape of their container), gas (fluids, fill up container they"re in), plasma (ionized gases in medium w/ charged particles) Mixtures are portions of matter w/ 2 or more chemical substances (referred to as constituents/components) homogenous mixture: uniform, same properties throughout (i. e. air, gasoline, soft drinks) heterogenous mixture: constituents are non-uniform (i. e. ramen, blood) Pure substances are homogenous, they"re forms of matter that contain one constituent substances single pure forms of matter; sometimes mixtures are referred to as substances (mixtures of substances) substance --> water, copper, sugar. 2. 3 - three levels of operation: observable, molecular, Observable level: direct observations from the human eye move on to molecules, atoms, and ions (their arrangement and movement) to understand what was directly seen.
