Through some research online, I found out that the sun's corona is hotter than it's surface. How's that even possible?? Is the sun releasing it's heat from the surface!!! Need a complete answer.

    $\begingroup$ Keep in mind that "temperature" and "heat" are separate things. The corona is very rarified compared to the surface; it may have a higher temperature, but I doubt it has a higher energy. $\endgroup$ – Asher Jan 26 '16 at 23:46

    $\begingroup$ What @Asher said. The corona's specific heat is probably very low. Water at 180F is considerably "hotter" (and more dangerous) than air at 180F, because water has a much higher specific heat. $\endgroup$ – barrycarter Jan 27 '16 at 0:25
  • $\begingroup$ @barrycarter that doesn't explain how heat flows from 6000k surface to several million K corona $\endgroup$ – Martin Beckett Jan 27 '16 at 4:06
  • $\begingroup$ You found it from your own research? What instruments did you use and how? $\endgroup$ – gerrit Jan 27 '16 at 11:14
