If you rubbed a piece of fluorite against a piece of feldspar, neither mineral would really change. Both minerals are relatively hard and have different chemical compositions, so they would not interact in a way that would result in a noticeable reaction.
Fluorite is harder than feldspar, so scratching fluorite against feldspar would cause the fluorite to scratch the feldspar. This means the fluorite would leave a mark on the feldspar, showing that fluorite is harder than feldspar.
The two minerals are likely to remain unchanged when placed in contact with each other. Fluorite is a soft, colorful mineral composed of calcium and fluorine, while feldspar is a harder, more commonly occurring mineral made up of aluminum and silicate. There would be no chemical reaction or interaction between the two minerals.
Fluorite is a mineral consisting of cubic crystals of calcium fluorite.
Rubbing cheese with a piece of paper can cause the cheese to absorb some of the paper's cellulose fibers, affecting its texture and taste. It is not recommended, as the paper may also leave behind particles that are not meant for consumption.
Friction strips electrons so the rubbed amber would take on a negative charge. Actually, friction causes charges to shift. Charges are indeed stripped from something, but they are collected up by something else. Amber does, indeed, become negatively charged by rubbing it with, say, fur. The phenomon is called triboelectric effect. And a link is provided.
If you rub a piece of fluorite against a piece of feldspar, you would likely observe that the fluorite leaves a streak on the feldspar due to its lower hardness on the Mohs scale. Fluorite has a hardness of 4, while feldspar ranges from 6 to 6.5, meaning feldspar is harder and would not be scratched by fluorite. The interaction may produce some fine dust from the fluorite, but it would not result in significant abrasion of the feldspar.
Fluorite is harder than feldspar, so scratching fluorite against feldspar would cause the fluorite to scratch the feldspar. This means the fluorite would leave a mark on the feldspar, showing that fluorite is harder than feldspar.
Well it would crack then it would get fractured... and if you have any Fluorite and Feldspar try it at home and then scratch it against a tile and watch what happens it looks really cool. i hope this helped you guys!

the # 5 would be scratched
When a balloon is rubbed with polythene, electrons transfer between the two materials causing the balloon to become negatively charged. The negatively charged balloon will attract the neutral piece of paper due to the electrostatic force between opposite charges.
A 'metal filing ' is a tiny piece of metal that is rubbed off from a large piece by a file.
When a straw is rubbed with a piece of paper, it acquires a positive charge due to the transfer of electrons from the paper. Two positively charged straws will repel each other. However, when a straw is rubbed with a sheet of paper, it acquires a negative charge, and opposite charges attract, resulting in the straws being attracted to each other.
The wood changes color
If you rubbed a mineral of hardness 7.5 against a piece of quartz, which has a hardness of 7, you would expect the harder mineral to scratch the quartz. The mineral with a hardness of 7.5 would leave a mark or scratch on the quartz surface, demonstrating the principle that harder materials can scratch softer ones. However, quartz would not be able to scratch the harder mineral in this scenario.
The silk picked up positive charges.
