Well, a magnet could DEFINITELY change if it gets exposed to heat, because you could melt the metal and change its shape.
If you hit it hard though, it wouldn't make much of a difference because the magnet is metal, so you'll probably just chip it or leave a dent.
Hope this helps ;)
They do this so that when you drink it or use it the contaminates that used to be in it dont make you sick

1) <span>Breaking Solvent-Solvent Attractions is an Endothermic Process.
2) </span><span>Breaking Solute-Solute Attractions is an Endothermic Process.
3) </span><span>Forming Solute-Solvent Attractions is an Exothermic Process.
Explanation:
When a solute is dissolved in solvent it either releases heat or absorbs heat depending upon the the interactions broken and interactions formed. At first, the solvent solvent interactions are broken , this process requires heat which is provided either from external source or is provided by the forming of solute solvent bond forming process which is exothermic.
When the solvent molecules get apart the solute particles enter to form interactions with elimination of heat. So, if the heat required to break solvent solvent interactions is greater than the heat provided by solute solvent interactions formation then the solute will not dissolve at room temperature and vice versa.</span>
