Therefore, with the given power output and frequency, the power absorbed in the water is 120 times greater than that in the coal. Since water absorbs microwaves and coal essentially does not, the energy concentrates in the wetter areas. In the water removal process, the power absorbed in the mixture decreases as evaporation nears completion.
