Liquids and Solids
Unit 1. Liquids
Understand the physical properties of liquids: vapor pressure, boiling point, surface tension and viscosity
Use the Clausius-Clapeyron equation to calculate the vapor pressure of a liquid at a given temperature.
Unit 2. Solids
Understand the physical properties of solids: vapor pressure, melting point
Define unit cell and lattice point.
Calculate the atomic radius of an atom given its density and type of crystal.
Identify key characteristics and examples of the major types of crystal: ionic, covalent, molecular, or metallic.
Unit 3. Phase Changes and Diagrams
Calculate the amount of heat lost or gained when a substance undergoes a series of phase and/or temperature changes.
Define phase boundary, triple point, and critical point.
Use phase diagrams to determine the phase of a substance at a given temperature and pressure.

Solids and Liquids
Bozeman Science - In this video Paul Andersen compares and contrasts the properties of solids and liquids. Solids have a more organized structure which can either be amorphous or crystalline. In liquids the intermolecular forces are lower and so the molecules can show translation. Some of the properties that can be observed in liquids are viscosity, surface pressure and volumes of mixing.
CrashCourse: In this episode of Crash Course Chemistry, Hank gives you the low down on things like London Dispersion Forces, Hydrogen Bonds, Cohesion, Adhesion, Viscosity, Capillary Action, Surface Tension, and why liquids are just... WEIRD!

Doing Solids: Crash Course Chemistry #33
CrashCourse: In which Hank blows our minds with the different kinds of Solids out there and talks about why they're all different and have different properties. Today, you'll learn about amorphous and crystalline solids, types of crystalline solids, types of crystalline atomic solids, properties of each type of solid, and that the properties depend on the bond types.

Unit Cell - Simple Cubic, Body Centered Cubic, Face Centered Cubic Crystal Lattice Structures
The Organic Chemistry Tutor: This chemistry video tutorial provides a basic introduction into unit cell and crystal lattice structures. It highlights the key differences between the simple cubic unit cell, the body centered cubic structure and the face centered cubic structure in table format. It provides the number of atoms per unit cell / coordination number, the atomic packing factor / fractional volume efficiency, and the formulas for the edge length calculation of each unit cell which can be useful to calculate the density of the crystal structure given the atomic radius and vice versa. This video is packed with information.
Find Unit Cell Edge Length (Given Density)
Find Unit Cell Edge Length (Given Density)
If you have the density of a metal and know its crystal structure, you can find its unit cell edge length. Here, I show you how it's done for Magnesium, which crystallizes in an FCC lattice
