Here's a breakdown:

* Particles in a liquid: The molecules in a liquid are constantly moving and colliding with each other. Some molecules have more energy than others.

* Escape velocity: If a molecule at the surface of the liquid has enough kinetic energy, it can overcome the attractive forces holding it to the other liquid molecules and escape into the gas phase.

* Vapor pressure: The rate of evaporation depends on factors like temperature, surface area, and the type of liquid. The higher the temperature, the more molecules have enough energy to escape.

* Equilibrium: As more and more molecules escape into the gas phase, some of them will collide with the liquid surface and re-enter the liquid. Eventually, the rate of evaporation and condensation become equal, reaching a state of equilibrium called vapor pressure.

So, yes, particles can escape from the surface of a nonboiling liquid and enter the gas state through evaporation.
