Question

what will happen if you rubbed a piece of topaz against the corundum

Answer 1

Answer:

There will be scratch on Topaz but not on Corundum

Explanation:

According to Mohs Hardness Scale, Topaz is at scale of 8, while Corundum is at scale 9. Greater the scale, greater is the hardness. Therefore Corundum is harder than Topaz. So, if Topaz is rubbed against a piece of Corundum, the corundum will scratch the Topaz but Topaz will not be able to scratch the Corundum.
