Abstract

The thermal pressure of gas in the Galaxy is relatively small compared to the total pressure, but the values and dispersions of this pressure in different phases of the medium can yield important diagnostics of turbulent and explosive processes, as well as the exchange of matter between the disk and halo. Diverse methods of measuring this pressure allow us probe conditions in cool, neutral clouds, the warm, ionized medium, and the hot gas in the halo, all of which are summarized here.
