Chemically yes, physically no. Microwaved water is more buoyant because it has a heat gradient and rarely boils properly. It tends to get superheated and explode rather than boiling.
This is why tea bags float on top of microwaved water but not boiled water.
I thought nearly any trace of minerals essentially reduced the likelihood of superheating down to near zero?
They do, it's pretty hard to get normal water to superheat, so OP's use of the phrase "tends to" is definitely misplaced. IIRC the MythBusters did a segment on that and they used distilled water. I think also re-boiling water might increase the odds of it happening, but I'm not sure.
Cool thanks for the confirmation :)
