What is the typical temperature of the intergalactic gas in rich clusters of galaxies?

Question

Quizplus · Accepted Answer

The intergalactic gas in rich clusters of galaxies typically has a temperature range of 10 to 100 million Kelvin (or K). This gas is heated to such high temperatures due to the gravitational energy released during the formation and evolution of the cluster. The gas is also affected by various physical processes such as shocks, turbulence, and magnetic fields. This high temperature makes the gas emit X-rays, which can be observed by X-ray telescopes.
