What gives a star its energy?
A star gets its energy from nuclear fusion in its core. In this process, hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the form of light and heat. This energy sustains the star and allows it to shine brightly.
What is the hottest part of a star?
It depends on how massive the star is and what part of its life its at. Most of the time the core is the hottest, but after a star runs out of its current fuel it will start fusing elements in a shell around its core out to the surface or photosphere. While these shells are burning they are the temporary hotspots of the star, while the core gets hotter and hotter.
How is energy generated in the core of a star?
Energy in the core of a star is generated through nuclear fusion, where hydrogen atoms combine to form helium, releasing a large amount of energy in the process. This energy production is sustained by the extreme pressure and temperature conditions found at the core of the star, which allow fusion reactions to occur.
How do stars make radiant energy?
Thermonuclear fusion in the core of the star heats the material of the star. A series of complex energy transfer mechanisms transport the heat from the core to the photosphere of the star. The photosphere then emits electromagnetic radiation.
What is the temperature of core of a star?
The temperature of the core of a star can reach millions of degrees Kelvin due to nuclear fusion reactions that generate immense heat and light. This intense heat and pressure in the core are what sustain a star's energy output.
What gives a star its energy?
A star gets its energy from nuclear fusion in its core. In this process, hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the form of light and heat. This energy sustains the star and allows it to shine brightly.
Why do stars cool when the fusion cycle gets to iron?
Unlike lighter elements, fusing iron consumes more energy than it produces. This does not, however, cause a star to cool. Once a star gets to the point of fusing iron, the core stops producing energy and without the pressure from the heat it produces, the core collapses while the rest of the star is blasted away in an explosion.
Where the sun gets its energy?
nuclear reactions at its core

How is energy generated in a star cores?
Energy in a star's core is generated through nuclear fusion, where hydrogen atoms combine to form helium releasing a massive amount of energy in the process. The extreme temperature and pressure in the core of a star make this fusion process possible, sustaining the star's energy output.
How does influenza get energy from food?
It gets its energy from phospholipids and polypeptides in the inner core of our tissues

What produces light in a star?
energy released during the process of nuclear fusion in the star's core
Why the temperature of the stars vary from one another?
The temperature in the core of a star depends, to a great extent, on:* The star's mass. The general tendency is that high-mass stars are hotter. * Where the star is in its life cycle. The star's core temperature will vary over time. On the other hand, the star's surface temperature also depends on its size. Thus, it is possible that PRECISELY because a star is hotter in the core, it gets bigger, and the surface temperature DECREASES (though its total energy output increases).
How is energy created in a stars core?
As with our Sun (a star) by nuclear fusion.
What is the temperature of core of a star?
The temperature of the core of a star can reach millions of degrees Kelvin due to nuclear fusion reactions that generate immense heat and light. This intense heat and pressure in the core are what sustain a star's energy output.
