What happens when the vapor pressure of the liquid becomes equal to the atmospheric pressure above?

Evaporation and boiling are both processes of converting a liquid into a gas, but they differ in terms of the conditions required and the rate at which they occur.

Evaporation occurs at the surface of a liquid when the molecules with sufficient energy escape into the atmosphere. It can happen at any temperature below the boiling point of the liquid. The process is influenced by factors such as temperature, surface area, and the presence of airflow. To observe evaporation, you can place a liquid in an open container and wait for it to gradually disappear over time.

On the other hand, boiling is the rapid vaporization of a liquid that occurs when the temperature of the entire liquid reaches its boiling point. This temperature is specific to each substance and remains constant during boiling. Boiling involves the formation of vapor bubbles throughout the liquid, which rise to the surface and release steam. To witness boiling, you can heat a liquid in a closed container until it reaches its boiling point, causing bubbles to form and the liquid to vigorously vaporize.

In summary, evaporation is a slower process that occurs at the surface of a liquid below its boiling point, while boiling is a faster process that occurs throughout the liquid when it reaches its boiling point. Evaporation can happen at various temperatures, while boiling only occurs at a specific temperature.
