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
A liquid with a high vapor pressure is said to be volatile, meaning it easily forms vapor at a given temperature. This characteristic is often associated with substances that have low boiling points.
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.
Water can exist in three main forms: solid (ice), liquid (water), and gas (water vapor). These different forms are dependent on the temperature and pressure of the surroundings.
Ethanol, for example, is liquid at room temperature.
The temperature at which the vapor pressure of a liquid equals the external pressure is called the boiling point. This is when the liquid changes into vapor at a constant temperature.
When water vapor forms liquid water droplets on a window, it is an example of condensation. This process occurs when water vapor in the air cools down and loses energy, resulting in the transition from a gas to a liquid state. The temperature of the window surface is lower than the dew point of the air, causing the water vapor to condense into droplets.
The temperature at which the vapor pressure of the liquid equals the atmospheric pressure is called THE BOILING POINT.
When the temperature of water vapor condenses into a liquid, it is called condensation. This process involves the conversion of water vapor back into liquid water due to a decrease in temperature.
