Thermal emissivity of gases

  1. Sep 12, 2008 #1

    Can anyone give me any information on where i could find information on the emissivity of a gas, particulally argon, or how i can calculate it??? i am trying to create a graph of heat transfer against temperature and see which plays a larger role at particular temperatures when transfering heat through a gas.

    Curiously with Argon being a rare gas and the observation that oxygen nitrogen and the rare gases do not emit radiation in the IR range of the EMR at ordinary temperatures the answer is the emissivity is very very low.

    Are you more interested in heat conduction by gases? See
    Also consider heat convection by gases.
