How does the process of boiling work?

Boiling is the process of turning a liquid into vapor by heating it. When a liquid is heated, its temperature increases and its molecules begin to move more quickly. As the temperature continues to rise, the energy of the molecules increases to the point where the attractive forces holding the molecules together are overcome, and the molecules break free and become a gas.

At the boiling point, the vapor pressure of the liquid equals the atmospheric pressure above it. When the pressure is lowered, the boiling point is also lowered, which is why water boils at a lower temperature at higher altitudes where the atmospheric pressure is lower.

Boiling is a type of vaporization that occurs on the surface of the liquid. The bubbles that form during boiling are actually pockets of vapor that are formed and collapse as they rise to the surface. The collapse of these bubbles creates the sound associated with boiling, and also creates turbulence in the liquid that promotes further boiling.

Boiling is an important process in many applications, from cooking to power generation. Understanding the science behind boiling is essential for many engineering applications such as the design of heat exchangers and boilers.
