HELP also how are they different?
Most likely, nothing would happen, although it's possible that the quartz could crack from thermal stress. Quartz usually forms hydrothermally - from water at high temperature and pressure - and contains small inclusions of water. On heating to high temperatures, this water can boil, causing quartz crystals to explode. For example, I have heard of quartz crystals exploding in kilns and fireplaces. Since quartz is hard, the temperature of a boiling pot of water should not be enough to cause crystals to explode. However, if you have a cluster of quartz crystals, the expansion of the quartz on heating and the contraction on cooling might loosen the crystals, causing the cluster to fall apart.
The highest temperature on your stove top isn't any where near warm enough to affect the molecular structure of quartz. You'd have to heat it up to at least 300 degrees C, and water wouldn't stick around on your stove top at that heat (neither would your stove top!).
If you add a carrot and half an onion with some salt and pepper, then at least it will taste like onions and carrots. I would not serve Quartz Soup to anybody without doing this. Bon Appetite!
quartz is chemically very stable and will not be chemically harmed by boiling, or even really exposure to most acids, bases, oxidants, and reductants (at near surface conditions). However, the quartz could (often does) contain tiny crystal defects that heating could cause to spread, so if you heat it in boiling water, there could be physical damage, crystals could break, or more likely, crystals could separate along the weak zones of contact (you could break individual crystals off from the main sample by accident).
