It depends on the type of liquid, though this transition is known as the boiling point (same as when a liquid forms a vapour).
Boiling Point
Ethanol, for example, is liquid at room temperature.
If the temperature of the liquid is raised, more molecules escape to the vapor until equilibrium is once again established. The vapor pressure of a liquid, therefore, increases with increasing temperature.
Water forms by the condensation of water vapor.
Q. What is the temperature at which a liquid changes to a gas or vapor?A. Boiling Point
The liquid vaporizes and the temperature increases as the volume also increases.
Liquid water is changed to water vapor by the process of evaporation (or boiling)Water vapor forms into clouds (liquid droplets) by the process of condensation
its always a liquid it is just in different forms
What forms is frost.
It forms a cloud
The temperature at which the vapor pressure of a liquid is equal to the external pressure is the boiling point. Evaporation is when vaporization of an uncontained liquid occurs.
The temperature at which the vapor pressure of the liquid equals the atmospheric pressure is called THE BOILING POINT.
