Answer:
The boiling point of a pure substance is the temperature at which the substance transitions from a liquid to the gaseous phase. At this point, the vapor pressure of the liquid is equal to the applied pressure on the liquid.
The boiling point at a pressure of 1 atmosphere is called the normal boiling point. The normal boiling point of water is 100°C, and remains constant until the water has vaporized.
The normal boiling point is high for liquids with strong intermolecular attractions and low for liquids with weak intermolecular attractions.
For a solution boiled at a fixed pressure, the composition of the vapor will usually differ from that of the liquid. In addition, the change in the liquid composition during boiling will change the boiling point.
