Soil and Soil Dynamics
In this video Paul Andersen explains how soils are formed and classified. Weathering of rock creates particles which are mixed with water, air, and organic material. Soils are classified according to particle size, chemical makeup, and...

Separating Solids
Separating Solids demonstrates that mixtures of solids can be separated based on their observable properties, including particle size, shape, color, and magnetic attraction.

Liquid-Liquid Extraction
Separation techniques are important in chemistry, and they won't always be as easy as filtration. Sometimes we need to separate two compounds that are dissolved in the same solution. Often we can take advantage of a difference in...

Types of Colloids and Their Properties
Earlier we learned that as far as mixtures go, we can have homogeneous solutions, or totally heterogeneous mixtures, where components don't mix. But there are actually intermediary mixtures, where substances mix to some limited degree....

De Broglie Wavelengths
You learned in the previous lesson in this series that a particle with momentum has the properties of a wave. So how about a baseball? The lesson calculates the wavelengths of different particles given their momentum (mass and velocity),...
