What heats the sun?
The heat generated in the sun comes from nuclear fusion reactions in its core, where hydrogen atoms are combined to form helium. This process releases a massive amount of energy in the form of heat and light.
Which type of fusion occurs in the red giant phase?
The primary type of fusion that occurs in the red giant phase is helium fusion. As the star's core runs out of hydrogen fuel, it contracts and heats up to the point where helium fusion can begin, converting helium into carbon and oxygen. This process generates energy and causes the star to expand and become a red giant.
What forces cause the expansion of the sun as it burns off its fuel?
The expansion of the Sun as it burns off its fuel is primarily driven by the balance between gravitational forces and the pressure generated by nuclear fusion in its core. As hydrogen is converted into helium through fusion, energy is released, creating outward pressure that counteracts gravitational collapse. Over time, as the hydrogen fuel diminishes, the core contracts and heats up, leading to increased fusion rates and causing the outer layers to expand. This process results in the Sun eventually becoming a red giant as it exhausts its hydrogen supply.
What keeps the sun shinning?
The Sun shines by converting hydrogen into helium through nuclear fusion in its core. This process releases a tremendous amount of energy in the form of light and heat, which is what gives us sunlight. This cycle has been sustaining the Sun's brightness for billions of years.
How do stars do fusion?
A star has a large mass, and when the gases of the star undergo gravity compression, they heat up enough to initiate fusion. Firstly by combining four hydrogen to make one helium, thus releasing some spare energy. So the star heats up further, and fusion of other elements becomes possible.
What is the cause of suns release of radiant energy?

Detonation of a fusion type hydrogen bomb is started by?
Detonation of a fusion hydrogen bomb is initiated by the primary fission bomb, which generates high temperatures and pressures needed to trigger fusion reactions in the hydrogen isotopes. The fission bomb compresses and heats the fusion fuel to the point where nuclear fusion reactions can occur, releasing vastly more energy than the fission reaction alone.
What gases are burning in are sun?
In the Sun hydrogen is converted to helium. Both are PLASMA. It's a very common misconception that the fusion in the sun happens with gas. However, the heat created by this fusion heats up the gasses so much that the individual electrons become loose from the atom. We call this state plasma.

What is a red giants core called?
A red giant's core is called a helium core. This is because as a red giant forms, the core of the star contracts and heats up, causing hydrogen fusion to transition to helium fusion.

What type of temperature of the star if it is red?
Low temperature because red giants are star with low temperatures, but very bright. A star forms when a portion of a dense interstellar cloud of hydrogen and dust grains collapses from its own gravity. As the cloud condenses, its density and internal temperature increase until it is hot enough to trigger nuclear fusion in its core (if not, it becomes a brown dwarf). After hydrogen is exhausted in the core from nuclear burning, the core shrinks and heats up while the star's outer layers expand significantly and cool, and the star becomes a red giant.
What trigger nuclear fusion in stars?
A star forms from a cloud of gas and dust that collapses under the force of gravity. As the cloud becomes more compressed it heats up, eventually becoming hot enough to fuse hydrogen.

What process does the sun do to give heat to earth?
The sun generates heat and light through nuclear fusion in its core. This fusion process converts hydrogen into helium, releasing vast amounts of energy in the form of heat and light. This energy is then radiated out as sunlight, which warms the Earth.
