However, OP asks: "does the boiling point of the water reduce due to the loweing of this air pressure over the surface". So he's not asking for boiling inside the water, but specifically for boiling at the water surface. And yes, dissipating energy into the water can obviously raise the temperature to the boiling point. This would probably take a while, though, and is no pressure effect. :) | |
