“Why is the corona hotter than the surface of the sun? Surface of the Sun is at about 10430 F, the atmosphere is 300 times hotter.
Answer; Velocity <=> Gravity sequence. Plasma is caught within two forces, velocity and gravity, yet, continuously heated from the surface of the Sun, elevate temperature of the Corona to the greater degree.
Density (scale of the density<=> plasma<=> heated gases) is also at play between velocity and the gravity.
The very same mechanism is reflected within human body; once body is submerged in hot water (yet, not too hot obviously), or in sauna, than temperature difference within internal organs as well as near the skin is causing heat sensation as well heat trapped between internal “velocity” and external surface we could compare as “gravity”.
In addition Earth atmosphere , yet, entire system is similar to the Sun’s Energy Broadcast, when it comes to temperature.

Questions that have long stumped scientists. “Why is the corona hotter than the surface of the sun? That defies the laws of nature,” she said. “We have not been able to answer these questions without actually taking a probe into the sun.”
