Air of high boiling point and/or rectification manner of blend of temperature sensitivity useful productAccording to the invention, a process for the rectification of mixtures of high-boiling air- and/or temperature-sensitive substances which require a high separation efficiency is proposed and in ...
The temperature at which a liquid changes to a vapor or gas. As the temperature of a liquid rises, the pressure of escaping vapor also rises, and at the boiling point the pressure of the escaping vapor is equal to that exerted on the liquid by the surrounding air, causing bubbles to for...

4.1 Boiling point, freezing point and melting point The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquids changes into a vapor. The boiling point depending upon the surrounding environmental pressure....
The boiling point for one type of liquid is almost always different from another type of liquid. For example, water requires a different pressure and temperature to transform into a vapor than mercury. The variation among the boiling points of liquids is caused by the bonds and forces among th...
True.The values of melting point, boiling point as well as latent heat depend on atmospheric pressure.
Boiling begins when the liquid is heated to the point at which the pressure of the saturated vapor above its surface becomes equal to the external pressure. The temperature at which a liquid starts to boil under a constant pressure is called the boiling point (Tb). Strictly speaking, Tb ...
