About Temperature

Beverly Lynds, Skymath Liaison, Unidata Program Center, P.O. Box 3000, Boulder, CO.


This temperature tutorialx was written for Project Skymath. The tutorial contains a historical development of temperature and the kinetic theory and includes the temperature of the universe.
There are lots of links to other sites including NASA's Cosmic Background Explorer Satellite.

Candle Flames in Microgravity

NASA pages discussing the USML Experiment.


The burning of a candle relies on thermal convection to carry away waste gas and draw in fresh oxygen. Convection is possible due to the differing densities of gases at different temperatures in a gravitational field. Hence, the study of candle flams in microgravity (near-zero gravity) is an area of rich and unusual phenomena.

Blackbody Radiation

The Virtual Laboratory (G. Bothun), University of Oregon, Eugene, OR.


Select a temperature between 3000 and 10,000 degrees, and see the Planck spectrum for that temperature plotted. Stars have a radiation pattern which is governed largely by this formula. The user can perform photometry on that curve by selecting either a blue, green, or red filter.
