During which process do particles escape the liquid state for the gas state?

The transition of particles from the liquid state to the gas state occurs during two main processes: boiling and evaporation. Among these, boiling is characterized by a rapid transition that occurs throughout the entire liquid when it reaches its boiling point, which is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure surrounding it. During boiling, bubbles of vapor form within the liquid and rise to the surface to escape as gas.

Evaporation, on the other hand, is a more gradual process that occurs at any temperature when particles at the surface of a liquid gain enough energy to overcome intermolecular forces and enter the gas phase.

While both boiling and evaporation result in particles escaping from the liquid state to the gas state, boiling specifically describes the process occurring at a specific point, while evaporation can occur at lower temperatures and does not require the liquid to be at its boiling point. Therefore, if you are considering rapid and uniform particle transition throughout the liquid, boiling is the clear choice.
