Phases Chem

In Phases we will investigate the differences between the main phases of matter: Solids, Liquids, and Gases, as well as aqueous.  We will get deep with melting points being the same temperature as freezing points, and how boiling points are the same as condensing points.

We will learn of gas pressure and air pressure, and learn to convert between several different units like kilo-Pascals, Atmospheres, and Pounds Per Square Inch.

A big part of gases is learning of the Kinetic Molecular Theory of Gases.  That is, what makes a gas a gas, and how do they stay gases, or how they can turn into liquids.

We’ll see how a barometer works, and we’ll get to “meet” one of my wife’s sisters, who is a witch!  We’ll even draw her into the notes!  Because of her, you will see that water can actually get cooler when it boils, and you will get a chance to put your finger into boiling water and not get burned.  But first, you will have to better understand what boiling is.  It’s not as easy as you think now, that’s for sure!

We’ll use table H (for happy) and learn about evaporating liquids and the reasons some evaporate quicker than others.

And, if that were not enough, we’ll learn to draw heating curves, cooling curves, and phase diagrams.  You’ll be understand them enough to say, at any given temperature and pressure, what phase a substance is.  You’ll also be able to understand how you can add heat to a substance but it won’t change temperature (sometimes) but it will at other times.  (way cool).

Get psyched, we’re nearly half way through already.
