Can you put rocks in the microwave?

Answer 1

Microwaves work by using electromagnetic radiation to excite water molecules in the food being heated. Unless an object contains some water, heating is not likely to occur, although some non-water molecules are also excited by the frequencies that excite water molecules.

Answer 2

The simple answer is, yes. Open microwave door, insert rock/s, close door. That's how you put rocks in a microwave. I'm assuming you are more concerned with what would happen if the microwave was turned on with rocks inside it. The rocks would heat up slightly and might even crack or if you're really unlucky they could violently burst apart or explode, but that would be VERY,VERY rare! Basically put - microwaves work by exciting water mollecules which creates friction and the water heats up. Thus, for anything to be able to heat up in a microwave, it must contain water. Rocks could be completely dry and would then not heat up at all, but usually a rock would have a tiny bit of moisture on its surface, especailly if it was lying on moist soil. In that case the rocks would heat up slightly. The rock could also have cracks in it, wich might so small that hey're invisible to the naked eye. These crack would normally contain some moisture. Heating such rocks would cause the moisture to boil and rapidly expand, this could crack the rock into pieces or even make it explode, but as stated above this would only happen in extremely rare cases.

Answer 3

No, it is not safe to put rocks in the microwave because they can heat unevenly and may explode, causing damage to the microwave and potential harm to individuals nearby. It is best to avoid putting any type of rocks or minerals in the microwave for safety reasons.
