Discussion Overview

The discussion centers around the phenomenon of the Sun's corona having a temperature in the millions of degrees Celsius, in contrast to the Sun's surface temperature of about 6000 degrees Celsius. Participants explore the implications of this temperature difference in relation to the laws of thermodynamics.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions why the corona's temperature is significantly higher than that of the Sun's surface, suggesting it may defy thermodynamic principles.
  • Another participant requests clarification on how this phenomenon contradicts thermodynamics, indicating a lack of familiarity with the topic.
  • A different participant proposes that the high temperature of the corona could be attributed to moving magnetic fields within the Sun, likening them to magnetic 'whips' that contribute to temperature increases when they interact at higher altitudes.
  • This participant also suggests that energy transformation within the Sun adheres to thermodynamic laws, implying that the observed temperature differences do not necessarily violate these laws.
  • A reference to Wikipedia is provided, suggesting it contains useful information on the coronal heating problem.

Areas of Agreement / Disagreement

The discussion reflects multiple competing views regarding the explanation of the corona's high temperature and its relationship to thermodynamic laws. No consensus is reached on the underlying mechanisms or implications.

Contextual Notes

Participants express varying levels of understanding of the topic, with some assumptions about the nature of thermodynamics and magnetic fields remaining unexamined. The discussion does not resolve the complexities of the coronal heating problem.

Why is the sun's corona temperature around millions of degrees celsius while the sun's surface is about 6000 degrees celsius?

Doesn't that defies the laws of thermodynamics?

Please elaborate on how it defies the laws of thermodynamics. I'm a bit of a newcomer on this topic.
 
This could be due to the moving magnetic fields of the Sun. I've always thought of it as a lot of magnetic 'whips' inside the Sun, bursting out into the corona, and when so many whips come together at that altitude, the temperature rises. Or, when new loops form and collapse, this will raise the temperature as well.

Energy is simply changing forms, which obeys the laws of thermodynamics.
