Our understanding about the air we breathe has changed dramatically through time. This illustrated timeline from the NOVA Web site tracks the changing thought on air and the creation of the Periodic Table of the Elements.

The transcript of a talk given on the syndicated radio broadcast titled "The Engines of Our Ingenuity." The story contrasts the lives and personalities of two scientific colleagues - Robert Hooke and Robert Boyle. Discusses their...

An exhaustive list of equations and formulas which are commonly used in thermal physics (including equations for triple point). Equations are organized according to category. Meaning of the symbols is clearly stated.

This site from the University Corporation of Atmospheric Research provides a lengthy page covering numerous topics including the difference between heat and temperature, the use of different temperature scales, thermal expansion, how a...

Students design and build a paper rocket around a film canister, which is used as the engine. An antacid tablet and water are put into the canister, react to form carbon dioxide gas, and act as the pop rocket's propellant. With the lid...

Students will use soda to explore how carbon dioxide is able to dissolve into liquid. They will learn about Henry's law, which describes how the solubility of gas into liquids is dependent on temperature and develop hypotheses about how...

Based off of the hit television show NUMB3RS, this lesson introduces students to the not-so-well known Benford's Law, which helps identify random number sets that may have been fabricated. Students learn about Benford's Law by exploring...

Students observe demonstrations, and build and evaluate simple models to understand the greenhouse effect, the role of increased greenhouse gas concentration in global warming, and the implications of global warming theory for engineers,...

Explore the concept of matter in this Spanish-language encyclopedia entry. This site features the properties of matter, the Law of Conservation of Matter, and other important features of matter.

Harriet Beecher Stowe threw gas on the fire of the slavery issue with the publication of her novel, Uncle Tom's Cabin. Read about her background as an abolitionist, and find out the influence her book had in the North and even in Great...

In this activity, students construct their own rocket-powered boat called an "aqua-thruster." These aqua-thrusters will be made from a film canister and will use carbon dioxide gas - produced from a chemical reaction between an antacid...

Discusses the development of a new rocket engine that operates by the ion propulsion as opposed to gas propulsion. Well written and great graphics!

Determine the heat that has been added to a gas in a process where the volume does not change. A video describing the problem can be found here: https://youtu.be/7jbuZlStfjo

Determine the internal energy in a sample of gas that goes through an isothermal compression.

Determine the heat that has been added to a gas in an isobaric process.

In this experiment students observe a combustion reaction and deduce the components necessary for the reaction to occur. They also see the relationship between pressure, volume, and number of molecules for gases.

This site includes brief Chemistry tutorials on how to simulate experiments illustrating a number of different topics.

In this module, you will learn why gases are not affected by intermolecular attractions! You will also learn about the properties of gases and the math associated with this special group of matter.

Reversible reactions, equilibrium, and the equilibrium constant K. Learn how to calculate K, and how to use K to determine if a reaction strongly favors products or reactants at equilibrium.

Mark Bishop describes how to use equation stoichiometry in this audio book. Detailed examples help to understand the conversions. Also find links to audio books for other chemistry topics.

The General Chemistry Virtual Textbook, or Chem 1, is broken into several sections covering various aspects of topics related to chemistry. This section deals with gases and specifically mole fractions and volumes.

Using understandable words and exceptional graphics, this page describes the transfer of energy by means of the convection process. Contains several links to related topics.

Float away with the answers to many frequently asked questions about gases. Understand Avogadro, reaction stoichiometry and more.

Lecture notes for a college chemistry course give the basic principles of KMT. Does get into some of the gas law derivations.
