A heterogeneous system (comprising different substances or different phases) may be anisotropic if the loss tangents of the components are considered. As a result, it can be expected that the microwave field energy will be converted to heat by different amounts in different parts of the system. This inhomogeneous energy dissipation means selective heating of different parts of the material is possible, and may lead to temperature gradients between them. Nevertheless, the pre… Web22 dec. 2024 · As the microwave is turned on, the solvent molecules (mostly water) absorb the energy from microwaves and start moving. Movement leads to random collisions between solvent molecules which generate heat. The constituents soluble in the water get separated from the solute phase.
Web12 feb. 2024 · The simple answer to this question usually goes a little something like this: Your microwave oven generates microwave radiation, which then agitates the water molecules contained in your food.
