Astronomy - space-craft


Expert: Tom Whiting - 7/3/2009

Question
Why do space-craft not melt in the heat of the million degree corona.?  

Answer
Hi Tina,
There is heat, and there is temperature...the two are not the
same.  You are confusing the two, as your question should have read,
Why do space craft not melt in the million degree temperature
corona?  There really isn't that much heat though.
Temperature is a measurement of the speed of the atoms and molecules
whereas heat is the quantity of energy.  So in the corona, the
atoms are zipping along at a very high speed (high temperature)
but there aren't very many atoms doing that, (it's nearly a vacuum
out there) so there isn't really that much heat to hurt spacecraft.

Another analogy is a campfire and a burning cigarette...both are
measured at around 1200 degrees F, but campfires have heat quantity,
(lots of wood burning) so while at the same temperature the campfire
will keep you warm with lots of heat, whereas the tip of a burning cigarette will not...yet both are about the same temperture.
Hope this helps,
Clear Skies,
Tom Whiting
Erie, PA
