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 both Boltzmann Distribution and the velocity of gas molecules.

Learn how to calculate the kinetic energy of a gas molecule, describe the relationship between the temperature of a gas and the kinetic energy of atoms and molecule, and describe the distribution of speeds of molecules in a gas. The...

By the end of this section, you will be able to state the ideal gas law in terms of molecules and in terms of moles; use the ideal gas law to calculate pressure change, temperature change, volume change, or the number of molecules or...

Explore the thermal behavior of gases, in particular, examine the characteristics of atoms and molecules that compose gases. Learn about the ideal law of gases in terms of molecules and moles. Multiple formulas and examples are provided.

By the end of this section, you will be able to express the ideal gas law in terms of molecular mass and velocity; define thermal energy; calculate the kinetic energy of a gas molecule, given its temperature; describe the relationship...

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?

This video segment adapted from Interactive NOVA profiles two scientists who were surprised in 1984 to discover a hole in our atmosphere's ozone layer as big as the United States. [3:47]
