What is Heat?
If we have 1000 atoms of Hydrogen and 500 atoms of oxygen and set a little spark to begin a reaction, what is the 'heat' of the exothermic release?
Let's see some physics behind what 'heat' is.
this can be observed"heat" is a relative term. heat is generated by friction and certain chemical reactions.
i would say the heat in your question would be the energy left after you subtracted the binding energy and light energy from the total energy liberated.

the idea being asked is can the 'heat' of each chemical reaction be defined in wavelengths (nm), rather than as joules/eV...?

and in a big scope a solar flare could be the sun transfering energyHeat is energy transferred from a hot body to a colder one.
So let's bottle it up and work on the definitionNo. Heat is energy.
and infrared is what.............?Wavelength is length.
i agreeHi Bishadi. Unfortunately, I'm no physicist but I think heat is something we all take for granted. There is perhaps more to learn about how heat is generated.
first half is agreed, but friction tells us nothing as to what HEAT is.We do know heat is EMR, and that heat is also friction.
i like your style here, as then the mass is not so much causing the 'heat' as much as the fields interactingOn Foucault's wheel, heat is generated by magnetic friction. The motion of the conductor generates heat as it passes through the electromagnet. The eddy currents on the conductor create an opposing magnetic field. The kinetic energy of the wheel in motion generates heat. This heat is the result of a drag force. It is the friction between two magnetic fields.
Almost like 2 planet could hit each others and a huge amount of the stuff described as 'heat' comes from the impact....A falling object will also generate heat. The terminal velocity of an object is the result of its opposing drag force. The increase in drag force increases the amount of heat generated. .
ahh.... so that transformation is what needs defining....Kinetic energy is turned into heat
If we know that heat is EMR, then perhaps, there is something we don't quite fully understand about kinetic energy. This could degenerate into a heavy philosophical discussion on Zeno's paradoxes, but it could be argued that kinetic energy is not a property of the object itself. In fact, it could be said that the kinetic energy is actually a property of the fluid which surrounds the object. I am of course referring to the aether.
I guess I'll have to sit down, and have a good think about how the above relates (if at all!!) with the chemical reaction of H and O.
r u the almighty salami of the world?What a bunch of silly, foolish people (especially the OP) - trying to discuss something when they don't even have a clue as to what they are talking about!
infrared is what?IR radiation - or any other waveband for that matter - is NOT heat!
the sun is just throwing magic stuff at us.And neither is friction - that's plain stupid. EM radiation is just another form of energy and certainly isn't heat.
most sense you ever wrote, that i can rememberFriction is nothing more than the physical resistance interaction between two materials in which one is moving - or attempting to move - across (or whatever) another. It most certainly can produce heat but is NOT heat in itself.
at what 'wavelength' are they vibrating at? (resonance)Simply and succinctly put, heat is the vibratory motion of molecules -
is this something we should write down, oh mighty salami?You people don't need to go back to college or even high school - you need to return to the lowest elementary school level - and PAY ATTENTION this time!!!!
Such displays of gross ignorance should be punished by a rap across the knuckles with a fast-swung ten-pound hammer.
