I'll give you an interesting experiment to try with a microwave. Buy a can of NesCafe instant coffee. Boil water in a cup in the microwave, and
boil more water on the stove. Add the same amount of instant coffee and the same amount of each type of heated water and stir.
Notice which water the instant coffee dissolves completely in, and notice which water it will not fully dissolve in, even if you wait a little
while.
I'll wait for your results.

BTW, I haven't noticed this difference with Folger's or Maxwell house, just NesCafe instant coffee.
Another interesting one is this (I actually had my son do this for a science project). Grow two sets of identical plants, in identical pots, in
identical soil. Feed one set of those plants tap water. Feed the other set water that has been heated to boiling (and left to cool to room
temperature) in a microwave. Notice if there is any difference.
You'll be surprised at the results.
