Radiant energy produces heat when it strikes matter.Is this true?
370272
Yes. Radiant energy strikes the matter surface it repel electrons from the matter and it release heat energy.

when things gain energy, their particles heat up and begin moving, but what also happens is that the electrons in the substance are given enough energy to jump energy levels. This is unstable, so they fall back down to their ground state and give off energy in the form of light (red hot, white hot).

Look, energy is conserved, period.  It may be in the form of PE, KE, heat, etc., but it is always conserved.  My best guess is that whatever experimentalists you're thinking of probably neglected to consider heat effects of some other energy drain/source.\n\nBy the way, I think you now hold the record for the worst spelling and punctuation ever on Yahoo! Answers.

Yes. It will superheat and have a violent reaction when something touches it.

Well yes and no. According the the principal of conservation of energy there is a set amount of energy and it can only be converted, not created or destroyed. But as we look into more complicated realms of physics, we understand that matter can be converted  into energy, and vice-versa.

I am assuming the energy in this context as "heat energy". Then the answer is NO. It depends on the temperature.\n\nHeat flows from body of high temperature to body of low temperature.\n\nImagine a small tank (10ltr) on second floor and a big tank with 100 lt on first floor. If we connect these, water flows from top tank to below tank.\nHeight is synonymous to Temperature.\nAmount of water is synonymous to Heat energy.\n\nPS: Another similarity is electricity.\nTemperature = height of water = voltage\nheat flow = water flow = current\nheat energy = amount of water = charge\nheat resistance = pipe resistance = electrical resistance

In physics, heat is defined as energy in transit.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, and then only in the direction of the colder body.\n\n\nfor elaborate details refer to the link below:\n\nhttp://en.wikipedia.org/wiki/Heat

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.

it's heat absorbed or radiated during a change of a phase at constant temperature/pressure.

It gets hotter, expands, and thins.  Eventually the radiation gets past it.  \n\nIf there is enough buildup of radiation from the core, you can have explosive effects.

I don't really understand what your question is.  In the first place, heat always flows from a warmer object to a cooler one.  That maximizes the number of possible arrangements of energy quanta, leading to an increased entropy.

Because the energy from the sun is not heat, but rather radiant energy, while the heat that rises is thermal energy.

Heat energy from the sun travels through radiation, as opposed to convection and conduction.

You should re-ask.  Do you mean strength or heat or both?  We also produce electricity and build chemicals that store energy.  You need to define output better.

well energy is used only in the beginning to start the reaction. otherwise an exothermic reaction will give out tremendous amount of heat energy.

Thermal energy is energy associated with temperature.  This corresponds to a measurement of how much the particles in a material 'wiggle'.  The more the wiggle the higher their temperature.  This wiggling causes the emmision of EM waves or light according to a blackbody curve.  Higher temps, with more wiggling, will emit more total energy and more photons at shorter wavelengths.  The hotter the object, the more infrared radiation it emits, however it will also emit more of every other wavelength too.  The peak wavelength shifts to shorter wavelengths ( higher energies) at higher temperatures.

Not only does it emit heat but it also emits infra-red radiation...
