Find out how real gases differ from ideal gases, and when intermolecular attractions and gas molecule volume matter.

A section in a college textbook exploring the ideal gas law in relation to molecules and in terms of moles. Learn how to calculate the variables in the ideal gas law. Also become familiar with Avogadro's number and how to use it to...

Examine the link between molecular motion and energy. Observe the movement of a molecule at room temperature. Learn about the different types of molecular motion.

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 light bulbs and their relation to information on movement of gases and...

The General Chemistry Virtual Textbook, or Chem 1, is broken into several sections covering various aspects of topics related to chemistry. This section seeks to answer the question, how far does a molecule travel between collisions?

The ideal gas law is an empirical law; it's a relationship between the pressure in a system of gases to the volume, the temperature, and the number of gas atoms/molecules in the system. This "law" is valid if the gas atoms/molecules are...

Atoms are very, very small. Atoms are so small that it is often said that there are as many atoms in a single grain of sand as there are grains of sand on all of the world's beaches - certainly a difficult thing to prove, but you get the...

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 random molecular motion and topics such as diffusion and effusion.
