The phase transition process in which a substance changes from a liquid state to a gas state

The process by which a substance changes from a liquid state to a gas state is called vaporization. The gentle form of vaporization that occurs at the surface of a liquid is known as evaporation. Characteristics of evaporation: (1) It occurs at the surface of the liquid; (2) It can take place at any temperature; (3) The vaporization process is slow; (4) Heat must be absorbed from surrounding objects

The process of vaporization that occurs on the surface of a liquid is called evaporation.

The process by which a substance changes from a liquid state to a gas state

The process of concentrating a solution by heating it to vaporize a certain component in the solution is called evaporation.

The process by which gas escapes upward from within a liquid once the liquid reaches a certain temperature is called evaporation

In modern Chinese, it is often used to describe people or things that abnormally appear to be on the verge of disappearing. Evaporation is the process of vaporization that occurs at the surface of a liquid. The evaporation of a solution generally refers to the process of vaporizing part of the solvent in the solution by heating, in order to increase the concentration of the non-volatile components in the solution (concentration) or to cause the solute to crystallize out of the solution. Generally, the higher the temperature and the larger the exposed area of the liquid surface, the faster the evaporation rate ； The lower the pressure on the surface of the solution, the faster the evaporation rate.

The liquid surface slowly transforms into gas
