Ok, I get a little bit of this, but I still think that the temperature and water would be enough to cancel out the friction heat, so as you said, physics wouldnt be able to do it all. I dont know though, Sanji was able to whip out a Diable Jambe against the kraken, so it may be possible with OP physics. As for the steroid volatility, that seems odd to me considering that the human body is 3/4 water or something like that. Maybe that was the reason Luffy is able to produce steam in Gear Second.
