its from a chemistry lab. the labs bout mixtures that are soluable or insoluable. i dont get it...

Phases consist of two or more substances from the following items that disperse in each other but do not form solutions: solids, liquids, gases. A common item is salad dressing that consists of water and oil. This would be two liquid phases. Smoke consists of solid particles in air. Fog is a two phase system consisting of water droplets dispersed in a gas - air. In these cases the two substances are different. Ice floating in water is a two phase system consisting of the solid and liquid state of the same substance.

Look at a bit of granite, and you will see that it contains a very large number of different mineral phases.
Or, if the word "phase" is being used in its other meaning of "solid, liquid, or gas", think of Styrofoam, solid with pockets of gas.
if you're thinking about solubility, mud is a heterogenous mixture of water and clay (which is not soluble in water), and the water and the clay are different phases, but sea water is a homogenous mixture of water and salts that are soluble in it, and is a single phase. Mayonnaise contains two different liquid phases (water and oil) that don't dissolve in each other. I hope that covers it for you.
Chemistry is fun, even if the textbooks sometimes make very heavy weather of the obvious at the beginning.

There are lots of metals, most metals that you have contact with, which are two or more phases. In this case the different phases are different crystall structures and different chemical compositions within a single piece of metal.
If you have a mixture of two things which are not completely soluable in each other, you will have two phases.

Some materials called colloids are not solutions or suspensions. The particles are sized between the 2.
sol is a liquid in a solid
gel, is a liquid trapped in a solid.
fog is a liquid in a gas
smoke could be a solid in a gas
paint is a solid suspended in a liquid
