Sal continues his explanation of the states of matter by focusing on hydrogen bonds. This time, he uses plasma as the substance being studied, and explains how the hydrogen bonds change as the substance goes from solid to liquid to gas.

A teenaged Jack Spangler demonstrates how reducing air pressure in a bottle can pull a boiled egg inside. Then dad does a similar demonstration using liquid nitrogen to reduce the air pressure. Even though the result is the same, the...

Create a cauldron of bubbling fun with this Halloween-themed demonstration idea. Using dry ice, Steve Spangler creates a crystal ball. If you compare the sublimation of dry ice to the melting of water ice, it is a wonderful way to...

In this episode of "Steve Spangler Science" videos, the gas produced by the sublimation of carbon dioxide dry ice creates a nice, fluffy cushion in a bowl of water. Since it is less dense than a soap bubble and cool enough to keep it...

There are four states of matter: solid, liquid, gas, and plasma. As this clip describes, the key to changing the states of matter is the addition or subtraction of energy. Learn about molecules, heat, plasma, and the science behind...

An extensive set of notes and graphics (excellent graphics) pertaining to the phases of matter, phase changes and the energy changes associated with changes in phase. Characteristic properties of solids, liquids and gases are discussed....

This lesson will explore a gas from a molecular viewpoint and describe its general properties. It is 1 of 2 in the series titled "Gas."

This lesson will define the three classical states of matter - solids, liquids and gases. It is 2 of 2 in the series titled "States of Matter."

In this episode of Crash Course Kids, Sabrina talks about what matter is and the three states of matter: Solid, Liquid, and Gas. She also does a quick experiment that you can do at home to prove that air is matter. [3:30]

A narrated screencast demonstrates the relationship between pressure and volume of a gas at constant temperature. [7:08]

In this Crash Course episode, Sabrina talks to us about matter and particles and that all matter is made up of particles. Also, she shows us how matter can change states from a solid to a liquid, a liquid to a gas, a gas to a solid, or a...

Examples and practice problems of solving equation stoichiometry questions with gases. [5:38]

See how an engine runs on fuel and air. [0:41]
