hi, i don't quite know how to pose this question but i'll try my best. if you have an object and heat one end of it, energy will move from an area of high energy, to an area of low energy. By this method, heat transfer will stop when all regions of the object are at the same temperature. (at least as far as i know, this is what will happen) so in a microwave, water molecules absorb energy in the form of 'microwaves'. if the energy of a photon is equal to planck's constant * it's frequency will the water molecule no longer absorb microwaves once it has the same amount of energy as the photons that hit it? i'm convinced i'm probably using 'classical' ideas etc to try and think about this, but i really don't know enough about photons and the like to make sensible assumptions. i was tempted to ask if the heating of the water has anything to do with electrons absorbing energy and changing 'energy level' - but i have a feeling that's not the case. so if anyone can explain to me whether my first idea is sensible or not, that would be great. P.S although my understanding of how a microwave works might be primitive, i'm really more interested in the actual absorption part of my question(s) thanks!
