What is boiling point? Written by Adeel Abbas Boiling point is defined as the temperature at which vapor pressure of a liquid becomes equal to the external pressure surrounding it. This means that when the external pressure is lower, boiling points are also lower and vice versa. Vapor pressure of a liquid depends on its … Read more
