energy released by the sun  results from the process wherein atomic nuclei?
491021
energy is released in the sun from a process called atomic or nuclear fusion. in this process, 4 hydrogen nuclei combine to form a helium nucleus. but the combined mass of 4 hydrogen nuclei is slightly less than the mass of a helium nucleus. this difference in the mass is converted into energy. this process is called nuclear fusion. at any given point of time infinite fusions r takin place inside the sun. this energy eaches us in the form of heat,light energy. this is together called as solar energy.

Mass and energy are different, but can be converted from one to the other. In the sun, nuclear reactions are continually converting small amounts of mass into large amounts of energy, which is light in all forms (from radio waves, through visible light, to gamma rays).\n\nPhotons are a pure form of energy, packets of electromagnetic radiation (sinusoidal electric and magnetic field waves travelling perpendicular to each other), that have no REST mass, but have momentum as they are travelling at the speed of light. This is what allows them to push solar sails.

You're tired and lethargic from being too hot and a little dehydrated. Probably a little sleepy and stiff from lying around too, if you're actually sunbathing.\n\nThe suns energy is electromagnetic radiation, that's not the same kind of energy your body runs on. Your body runs on chemical energy, that is, energy derived from breaking down chemicals.\n\nThe sun's energy comes from fusion reactions.\nA fusion reaction is when two atomic nuclei (the part in the middle of an atom) are joined into another heavier element.\n\nOur sun is a medium size main sequence star. Which means that it isn't too big, and that it's in the prime of it's life. It fuses hydrogen into helium for the most part. \n\nWhen a fusion reaction happens not all the mass of the two atoms from the beginning goes into the final single atom, the rest flies off as radiation. The radiation excites the atoms in the sun and they give off the electromagnetic radiation that we receive.

These particles include atomic constituents such as electrons, protons, and neutrons (protons and neutrons are actually composite particles, made up of quarks), as well as other particles such as photons and neutrinos which are produced copiously in the sun. However, most of the particles that have been discovered and studied are not encountered under normal earth conditions; they are produced in cosmic rays and during scattering processes in particle accelerators.

In physics, nuclear fusion is the process by which multiple nuclei join together to form a heavier nucleus. It is accompanied by the release or absorption of energy depending on the masses of the nuclei involved. Iron and nickel nuclei have the largest binding energies per nucleon of all nuclei and therefore are the most stable. The fusion of two nuclei lighter than iron or nickel generally releases energy while the fusion of nuclei heavier than them absorbs energy; vice-versa for the reverse process, nuclear fission.\n\nNuclear fusion of light elements releases the energy that causes stars to shine and hydrogen bombs to explode. Nuclear fusion of heavy elements (absorbing energy) occurs in the extremely high-energy conditions of supernova explosions. Nuclear fusion in stars and supernovae is the primary process by which new natural elements are created. It is this reaction that is harnessed in fusion power.\n\nIt takes considerable energy to force nuclei to fuse, even those of the least massive element, hydrogen. But the fusion of lighter nuclei, which creates a heavier nucleus and a free neutron, will generally release more energy than it took to force them together — an exothermic process that can produce self-sustaining reactions.\n\nThe energy released in most nuclear reactions is much larger than that for chemical reactions, because the binding energy that holds a nucleus together is far greater than the energy that holds electrons to a nucleus. For example, the ionization energy gained by adding an electron to a hydrogen nucleus is 13.6 electron volts -- less than one-millionth of the 17 MeV released in the D-T (deuterium-tritium) reaction shown to the top right.\n\nThe steps of the main cycle of nuclear fusion in stars were worked out by Hans Bethe.

The protons and electrons formed into stellar bodies. The stellar bodies converted the hydrogen into helium, carbon, nitrogen, and some other lighter elements.   \n\nStars with a mass of more than 5 solar masses are subject to becoming supernova--a massive stellar explosion.  The energy produced by that explosion produced all of the heavier elements and distributed them throughout the galaxy where they were captured by other gravitational fields.

You are correct, the Sun is just too big. In fact, nuclear fusion reactions that occur for a fraction of a second in a thermonuclear bomb explosion are continuously occurring in the core of the Sun, and the amount of energy is similar to what would be produced by detonating 100 BILLION H-bombs every SECOND. Our bomb technology does not come anywhere near equaling that, much less overwhelming it to blow up the Sun!

Nothing. Even geothermal energy (heat from the center of the Earth) originally came from the Sun.

The Sun is the most prominent feature in our solar system. It is the largest object and contains approximately 98% of the total solar system mass. One hundred and nine Earths would be required to fit across the Sun's disk, and its interior could hold over 1.3 million Earths. The Sun's outer visible layer is called the photosphere and has a temperature of 6,000°C (11,000°F). This layer has a mottled appearance due to the turbulent eruptions of energy at the surface. \nSolar energy is created deep within the core of the Sun. It is here that the temperature (15,000,000° C; 27,000,000° F) and pressure (340 billion times Earth's air pressure at sea level) is so intense that nuclear reactions take place. This reaction causes four protons or hydrogen nuclei to fuse together to form one alpha particle or helium nucleus. The alpha particle is about .7 percent less massive than the four protons. The difference in mass is expelled as energy and is carried to the surface of the Sun, through a process known as convection, where it is released as light and heat. Energy generated in the Sun's core takes a million years to reach its surface. Every second 700 million tons of hydrogen are converted into helium ashes. In the process 5 million tons of pure energy is released; therefore, as time goes on the Sun is becoming lighter. \n\n\n\nThe chromosphere is above the photosphere. Solar energy passes through this region on its way out from the center of the Sun. Faculae and flares arise in the chromosphere. Faculae are bright luminous hydrogen clouds which form above regions where sunspots are about to form. Flares are bright filaments of hot gas emerging from sunspot regions. Sunspots are dark depressions on the photosphere with a typical temperature of 4,000°C (7,000°F). \n\nThe corona is the outer part of the Sun's atmosphere. It is in this region that prominences appears. Prominences are immense clouds of glowing gas that erupt from the upper chromosphere. The outer region of the corona stretches far into space and consists of particles traveling slowly away from the Sun. The corona can only be seen during total solar eclipses. (See Solar Eclipse Image). \n\nThe Sun appears to have been active for 4.6 billion years and has enough fuel to go on for another five billion years or so. At the end of its life, the Sun will start to fuse helium into heavier elements and begin to swell up, ultimately growing so large that it will swallow the Earth. After a billion years as a red giant, it will suddenly collapse into a white dwarf -- the final end product of a star like ours. It may take a trillion years to cool off completely. \nhope this works, go to the web site, too, just to see for yourself. good luck

sun has huge amt of hydrogen atom which under the high temp. undergo nuclear fussion reaction to produce helium ion with emission of huge amount of light & heat......so becoz of this light it always shine...& bcoz of that heat the nuclear reaction keep to continue......

I'm going to focus on the word "producing" here.  The sun produces heat and light through thermonuclear reactions in its core.  If those reactions were to stop tomorrow, it would take hundreds of thousands of years for us to find out.  Maybe scientists who study the sun would know sooner.  Energy that is produced in the core has to collide with an immense number of particles on its way to the surface -- so many particles that it takes about one million years for this light to make it to the surface.\n\nEven if the reactions that power the sun stopped tomorrow, it would go on shining for roughly a million years.  No one in our lifetime, or for many generations to come, would be the wiser.

In essence, the sun is a gargantuan nuclear fusion reactor. It uses hydrogen as its fuel, the fusion process creates helium, which is lighter than hydrogen. Witin the sun, hydrogen is 'falling' toward the core, as helium is rising to the surface, causing convection currents. This is what gives the sun its mottled appearance. Sunspots occasionally occur, these oddities are associated with geomagnetic storms which send tons of radiation hurtling into space as a solar flare, or a larger coronal mass ejection. When this radiation interacts with our magnetosphere here on earth, spectacular light shows ensue around the poles...the Aurorae. These bursts of electromagnetic energy also play havoc on radio reception. The sun is a complex engine of massive power and energy, but it's still in essence a fusion reactor.

Jupiter's internal energy is  the release of heat trapped when it formed

Nuclear fusion is what you are talking about.  Basically smaller atoms (hydrogen for example) are smashed together under high energy to form larger atoms (helium for example).  In the process, a small amount of energy is given off.  This is the process that powers the sun, and if we could harness it, it would make a great source of electricity.  Anyway they have experimental fusion reactors, they just take in more energy then they give out making using them as a power source pointless.  They're working on that though.  Someday hopefully they can make a fusion reactor that gives off more energy then it takes in.

Atoms are the building blocks from which matter is formed. Everything around us is made up of atoms. Nuclear energy is contained within the center of the atom in a place known as the nucleus. Particles within the nucleus are held together by a strong force. If a large nucleus is split apart (fission), generous amounts of energy can be liberated. Small nuclei can also be combined (fusion) with an accompanying release of energy. Using this strong force that holds the nucleus together to produce energy is essentially what the field of nuclear power generation is about.\n  In the fission process certain heavy elements, such as some forms of Uranium, are split when a neutron strikes them. When they split, they release energy in the form of kinetic energy (heat) and radiation. The process not only produces energy but also additional neutrons that can be used to fission other Uranium nuclei and start a chain reaction.\n  In fusion, nuclei of light elements are brought together under conditions of high pressure and temperature, causing them to combine and produce new elements and energy.

well\n\nlets take an example\n\nthe sun radiates solar energy. it is then trapped by plants and made into chemical energy through photosynthesis. and then  the plant is eaten by an animal. the energy is then converted to heat energy and lost to the environment due to movement.\n\nso, you see. energy is not created or is it destroyed but it changes state as it moves in the biosphere. this is called conservation of energy.
