Question

The sun is surrounded by a white cloud of gaseous material called the corona. It is shown here, during a solar eclipse. The T of this plasma cloud of ions, protons, and freely moving c's is in the 10^60 C range. Its value determined by analysis of the identified ions, & the energy that it takes to create these ions in particular. The presence of Fe^14+ has been detected, and the conversion of Fe^13+ rightarrow Fe^14+ requires 3.5 times 10^4 KJ / mole. Using an estimate of 1.5 RT for the KE of 1 mole of Fe^14+ calculate a T for the sun's corona.

Explanation / Answer

The sun is surrounded by a white cloud of gaseous material called the corona. It
