Hello, i wanted to ask a few questions about science, that i cant find in google (im handy with it) Lets say, i have an iron chunk, like 10cm x 10cm, if i grind it for lets say infinite time, will it become liquid(?), something like if i grind it to maximum possble level? Another one i thought for some time, is does explosion effect stack? For example, i have 1 TNT stick, and i detonate it under ground, and it blows 1m x 1m hole (spherical). Now lets say i have 10 TNT sticks, and i detonate it underground aswell, so it will be perfectly 10x bigger than with 1 stick?
