microwaves are heat. it is a proven science fact beyond question. anyone who thinks differently is unscientific. hmmmmmm?

That is exactly why they use them in those convenient little ovens.

Hmmm lol ...

well were is the scientific link that proves your statement!!!!!

geeez. i can't seem to find one. stuartallsop and howard roark assured me this was the case, ...and well, ...you know those guys are just so smart i knew that they were right. just thought all the other (non
)scientists might get a laugh out of this.

does anybody agree that microwaves ARE heat? cause i'm pretty sure they're electromagnetic waves that cause things to heat up by causing high speed excitation of the particles(usually the water, according to my owner's manual, HAHA!).

and i'm pretty sure heat is a relative term, too.

Microwaves excite molecules...causing friction between them...that is heat...elementary.

darn it. gg, you totally beat me to it.

true. they CAUSE heating. they aren't heat. they're electromagnetic waves.

Heat is not the same thing as temperature.

Heat is a measure of the energy in a molecule.

Microwaves are energy. When they are absorbed by a molecule, the heat increases. Sometimes the temperature changes, sometimes it doesn't. ussulaly it does. but it is possible to change the heat without changing the temperature.

Actually, heat is the transfer of energy from one molecule to the next.

Temperature is the measure of average kinetic energy of a molecule.

So, the difference of average kinetic energy in a molecule and its neighbor, if different, will cause a transfer of energy, which we notice as heat.

So microwaves are a transfer of energy from the magnetron to the water molecules, i.e. heat.

'heat' usually refers to electromagnetic radiation in the infra-red wavelentgh.

microwaves are a different wavelength.

depending upon the context, heat and energy may be synonomous terms.

since microwaves are electromagnetic radiation (like heat, light, radio waves, UV rays, and gamma rays), they are energy.

and heat.

so microwaves are heat.

heat: 1. a form of energy associated with the motion of atoms or molecules in solids and fluid media by conduction, through fluid media by convection, AND THROUGH EMPTY SPACE BY RADIATION. (from the american heritage dictionary.)

WOW!!! microwaves ARE heat! i was wrong. you learn something new everyday.(if your willing).
as a good little scientist, i have no problem admitting it. i was wrong.
this is fun.

The General is right. Infrared radiation is commonly refered to as 'heat'. Unless you count all kinds of electromagnetic radiation (visible light, rntgen, etc.) as heat, microwaves are not heat. The microwaves in your magnetron is electromagnetic radiation that has exactly that frequency to excite the water molecules in your food (or whatever you put in your magnetron). That frequency is about 2.5Ghz or 2.5*10^9 Hz. Infrared is between 10^12 and 10^14.
