This week we will get started with cirriclium! The stuff we learn is HERE on my website, and due dates for the WHOLE UNIT are on Schoology.

Unit Overview
Unit Overview
In our final unit of the semester we will explore he different states of matter: solids, liquids, gasses, and even plasma. All elements and compounds can exist in any of these 4 states, but we tend to think of some matter as belonging to one of those states. Metals we experience mostly as solids, but they can easily melt and even turn into gasses at high enough temperatures. Oxygen and Nitrogen we often experience as gasses, but can be made into liquids by changing temperature and pressure, like how propane can be a gas in a propane tank.
We will spend most of the unit exploring gasses and their properties. Gases are significantly different than solids and liquids, and are the easiest of the states to explore in a lot of detail. The behavior of gasses is controlled mostly by an idea called Kinetic Molecular Theory. KMT is a model that describes how the particles in a gas behave, and can therefore explain how properties like pressure, temperature, and volume of gasses work. This theory leads to a lot of equations that can explain these properties to gasses, known as gas laws, which might be one of the biggest mathematical challenges we face this semester!
In the last section of this unit we will explore the properties of solids and liquids. Kinetic Molecular still explains the behavior of the particles in solids and liquids, but with some extra rules added to account for the fact that these particles are MUCH closer together and therefore stick together. The forces that hold these particles together, known as intermolecular forces, are what make solids and liquids so much different than gasses. We will explore these IMF's and learn about how they changes the properties of matter.
