Is that really a "water resonance"??...
Alternatively note that a microwave oven heats up the water in the food.
Yes, that is a resonance phenomenon where the microwave energy is absorbed by the OH bonds in the water molecule.
...
Is this question related to some sort of energy production from water? If so I would recommend you to drop your plans rather sooner than laterWhat is the resonance energy of water ( joule/mole)
are there tables or equations for calculations?
I mentioned Bertus because of the MRI connection.Is that really a "water resonance"??
Heat also heats up water in the food, and that is a different wavelength(s) than a MWO magnetron.
I thought the heating effect was simply a result of hitting the food with enough energy?
It's a lot of energy in a enclosed with a molecule (water) that's a good dielectric with a lopsided charge distribution. The water molecule rotates as the electric fields changes so now you have voltage, current (charges in motion) flow and power that mainly seen as resistance heating of the food and water. There are frequencies where the rotation speed matches the rate of voltage change so just as the molecule spins one way the field reverses and pushes it around in a circle like a flywheel.That sounds more like it.
Sorry Studiot I'm not buying the "microwave oven resonant frequency of water" theory. It's just lots of energy into an enclosed space.
Interesting! I've never heard that.... There are frequencies where the rotation speed matches the rate of voltage change so just as the molecule spins one way the field reverses and pushes it around in a circle like a flywheel.
That's all there is to resonance. Perhaps I should have said that the energy supply needs to be continued (not continuous).Resonance is an effect where the transfer of energy from one system to another is greatly enhanced by supplying the energy at the appropriate frequency. (Micorwave in the case of water).
If you bash something with a hammer, it does not matter what material you bash with it. The response is, in general, the same.I can certainly see the logic in RB's argument.
Don't do it on my account. I'm just happy I can have a hot cup of coffee in about 2 minutes.Since we seem to have left the OP far behind I am quite happy to explain the chain of events connecting these three issues.
My response was a simplification of a much more complex process of energy transfer by rotational torque. Resonance increases the absorption efficiency. If you bash a lump of clay how much energy is in the clay and how much energy is actually transfered to the surface the clay as resting on?I thought heating occurs in a substance is a repsonse to poor efficiency? So if you bash on a spring at resonance it is efficient and doesn't heat the spring very much. Energy is input, and then returned. But if you bash on a lump of clay it is very inefficient and causes the clay to heat?
