All transformations of energy involve A. the use of sun B. organization of atoms C. movemet of electrons?

The key here is the wording.  Transformation means change, and the sun's energy always arrives as radiation.  The organization of atoms is also constant - numbers of neutrons and electrons vary, but protons for each atom do not, and each particle stays basically where it should.  Movement indicates a potential for change -- electrons "jump" to your finger from a doorknob or from charged clouds to the ground, as lightning. C

Physical changes only change the appearance of the substance eg - water turns to ice or turns to water vapor is a physical change. The atoms are not rearranged. This kind of reaction is easy to reverse.\nChemical changes actually changes the chemical substance, and its characteristics and require much energy to occur. eg - hydrogen and oxygen combine to form water (H2O). these reactions are very hard to reverse. The atoms are rearranged. \nMarina.

heat is a manifestqtion of every kind of energy. Energy comes from movement of particles.  \nIn physics, heat is defined as energy in transit.[1] Generally, heat is a form of energy associated with the motion of atoms, molecules and other particles which comprise matter. Heat can be created by chemical reactions (such as burning), nuclear reactions (such as fusion taking place inside the Sun), electromagnetic dissipation (as in electric stoves), or mechanical dissipation (such as friction). Heat can be transferred between objects by radiation, conduction and convection. Temperature, defined as the measure of an object to spontaneously give up energy, is used to indicate the level of elementary motion associated with heat. Heat can only be transferred between objects, or areas within an object, with different temperatures.

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.

No more than the earth does work orbiting the sun. An orbit has constant energy, and if it is not circular, there is a continuous process of exchanging kinetic energy with potential energy while the sum stays the same.

As long as we understand, energy can take different forms but it can not be destroyed.  It can be converted to mass, and vice-versa.  There are other forms of energy such as light energy, chemical energy.  It seems that energy is exhibiting higher dimensions of space and what we see within our 3D world is translated to our braind as energy.

Nature is all about entropy or conservation of energy.  Stars of which Our Sun is one start their life as large balls of Hydrogen gas.  Due to the friction of the untold number of molecules  moving about, heat is developed- just like rubbing Your hands together.  The inside temperature of the Sun is about 2 million degrees.  It takes more energy to maintain 4 atoms of hydrogen than it does for one Helium.  With all the heat in the star's core it is possible for the hydrogens to form a helium by the process of nuclear fusion.  6 hydrogens take part in the reaction but two are recovered so the net result is 4h>1He.  This reaction results in the saving of 0.6% energy which works its way to the surface and radiates out into space.  Within the Sun it is estimated that about 745,000 tons of H are converted every second.  This number varies a bit when one reads the literature, but whatever the actual number is it is huge.

1.Heat is electromagnetic radiation and by using a photocell you could transfer heat into electric energy.\n2.You can also employ a thermocouple to generate some electricity\n3.A steam and Sterling engine can serve as good examples of heat changing into mechanical energy.\n4.Heating and cooling two co-joined metal strips of different linear expansion into buckling and relaxation. \n5.There more examples.

photophosphorylation, the light reactions, where the sunlight is exciting all the electrons. it's literally the electron transport chain plus some other stuff. electrons travel down a chain of proteins, releasing energy and creating ATP from ADP. however, in photosynthesis the electrons can go through it multiple times b/c they may be renergized by sunlight at the end. the electrons which aren't reenergized go on to the Calvin-Benson cycle. in respiration, at the end of the ETC electrons are used to form water.

This question could be interpretted two different ways: (1) What drives the sun to produce heat/enegery? and (2) Describe the process of using the solar energy to power modern conventions.\n\nSomebody else already attempted the latter, so I'll go for #1.\n\nThe sun, right now, is fusing hydrogen into helium to produce its energy.  It's been doing this for a long time, and will continue to do so until it runs out of hydrogen.  When this happens, it'll start fusing the helium, and so on.\n\nHope this helps.

Oxygen is required for combustion, not for nuclear reactions.\nIn Sun, the tremondous amount of energy is released by nuclear fusion reaction in which two hydrogen atoms combine to give a helium atom. A very small mass is converted into large energy, given by the famous equation: E=mc^2, where m is the difference in mass and c is speed of light.

If you're talking about a thermodynamically endothermic rxn, then PHOTOSYNTHESIS is a good example. Photosynthesis needs to be powered by solar energy in order to work. All endothermic processes need energy INPUT to urn. Conversely, exothermic rxns can happen spontaneously and release energy as product.

Of course energy is transferred  in energy transformation . How heat can be transferred in mechanical energy transformation or chemical energy transformation . There are  different type of energy like mechanical energy , heat energy, chemical energy and nuclear energy .  The Energy transform in  form of  qunta. Minimum energy transferred will be   h f ( frequency) . h is Planck's constant .
