Answers:Solid, liquid, and gas are three phases of matter, determined by temperature and pressure. When a substance is solid it is locked into a specific form. This is the coldest form; heat is just a measurement of how much the atoms 'wiggle', and they are wiggling so little that they stay in a set pattern. As the atoms wiggle a little bit more they get enough energy to break free, but they are still somewhat attracted to one another, so they roll all over each other, and you get a liquid. As they get even more energy and move faster and faster they overcome that force of attraction and are moving so fast that they can't 'grab on' as they pass one another, and you get a gas. Pressure plays into it too. For example, water expands when it freezes, so if it is under a lot of pressure it won't freeze even if it's cold enough, because the pressure keeps it squished into liquid form. This is why there are some lakes miles under the ice in Antarctica; the water is below freezing, but the weight of the ice sheet stops it from freezing and expanding. Homogeneous and heterogeneous refer to mixtures. A mixture is a bunch of stuff which exists all mixed together but which doesn't combine chemically. A Homogeneous mixture is uniform; that is, the same all throughout. You won't see layers in this, everything is evenly spread out. Heterogeneous mixtures have more than one phase. There are further subdivisions. A colloid looks homogeneous, but, microscopically, it is heterogeneous. Milk is an example of a colloid. The particles which are dispersed in a colloid are very small (between one nanometer and one micrometer). In milk, these dispersed particles are little globs of fat which have been emulsified. Heterogeneous mixtures with particles larger than 1 micrometer are called suspensions. These particles are big enough to fall out all on their own; this is called sedimentation. An example would be flour mixed with water; the flour will all gather at the bottom if you let it sit long enough. Homogeneous mixtures with a solvent and a solute is called a solution. The solutes are particles smaller than one nanometer, and the solvent is the continuous medium (usually a liquid) which surrounds them, dissolving them. Salt water is an example of a solution. There are many different types of these (A colloid of a liquid dispersed in air is an aerosol, a suspension of a gas dispersed in a solid is a foam, etc.), but that's the basic gist of it.
