restated: Why does not the very source of the sun's heat melt it's core?

Question

I understand that it will eventually burn out. But why does the very heat it gives off not melt the source of the heat?
Anything on earth will melt if it gets hot enough, why not the sun, it's nucleus.
There is something I am missing here.
Is it, in fact, melting but is just so large that it will take billions of years to melt the core completely?
Thanks.

Answer 1

It's core is already melted. It's made of plasma. The energy in the core is so intense that it causes the atoms to shed their electrons. And also, energy cannot be melted. It can only change form (such as heat, which is one form of energy).

Answer 2

The sun is a plasma-when heated solids turn to liquids, which turn to gases which in turn become plasma's (atoms stripped of electrons). It has a surface temperature of circa 5000C and a core temperature of 20000000C which at the pressure in the sun is sufficient to permit a continual thermo nuclear fusion reaction (just like in a hydrogen bomb but over the course of some 9 billion years. it is currently about half wat through it's life cycle. it will eventually use up the hydrogen fuel, collapse somewhat before the core becomes hot enough to sustain helium fusion and this will raise the core temperature to 100 million degrees, the outer layers will expand, engulfing the inner rocky planets.the helium fusion will only last a couple of million years before the star will collapse under gravity and eventually for a brown dwarf star

Answer 3

The sun's core is WAY beyond melted! It is believed to be mostly a plasma--electrons and atoms stripped of most if not all of their electron shell, moving around freely. What keeps the core stable is the immense pressure generated by the gravitation of the sun and the column of superhot gas over it.

According to current theory, the sun's core has to be in plasma state before it can ignite itself...

Answer 4

The very source of the sun's heat already did melt its (no apostrophe!) core! Read a high school book about the sun!

Answer 5

The sun is mostly Hydrogen gas and its in liquid form. It can't melt. The earth core is molten rock and can't melt. Hope this helps. Be Cool !!!

Answer 6

The sun is not made of any solid material. It is a combination of gasses that are combining via the process of nuclear fusion and thereby releasing tremendous amounts of energy as it converts the gas to energy.

Put simply, there is nothing there to melt.
