The normal boiling point is the boiling point at sea level, or more precisely, at 1 atmosphere pressure. At higher elevations, or at lower atmospheric pressures, the boiling point is lower. At higher...
I'm pretty sure the answer is that the normal boiling point means the substance is under "normal" or standard conditions. So the boiling point of the substance at a pressure of 1 ATM or 760 torr...
The Boiling Point is the point at which a substance at liquid state boils. The temperature that the liquid has to reach to be at Boiling Point (B.P) ranges, it is different for each liquid. The B.P...
