[[Boiling]] is a bulk phenomenon that occurs when a liquid is heated to its boiling point, causing bubbles of vapor to form within the liquid and rise to the surface. The boiling point is the temperature at which the vapor pressure of the liquid equals the external pressure surrounding the liquid.
[[Boiling]] is the rapid vaporization of a liquid, which occurs when a liquid is heated to its [[boiling point]]. At this temperature, the vapor pressure of the liquid equals the external pressure surrounding the liquid, allowing bubbles of vapor to form within the liquid.

[[Sublimation]] is a type of vaporization where a solid changes directly into a gas without passing through the liquid phase. This process is common in substances like [[dry ice]] (solid carbon dioxide) and is used in various industrial applications.

Vaporization[edit]

Bromine vaporizing from its liquid state.

Vaporization is the process by which a substance changes from a liquid or solid state into a gas. This process can occur through two main mechanisms: evaporation and boiling.

Evaporation[edit]

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. This process happens at temperatures below the boiling point of the liquid. Evaporation is a crucial part of the water cycle, contributing to the formation of clouds and precipitation.

Boiling[edit]

Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point. At this temperature, the vapor pressure of the liquid equals the external pressure surrounding the liquid, allowing bubbles of vapor to form within the liquid.

Sublimation[edit]

Sublimation is a type of vaporization where a solid changes directly into a gas without passing through the liquid phase. This process is common in substances like dry ice (solid carbon dioxide) and is used in various industrial applications.

Factors Affecting Vaporization[edit]

Several factors influence the rate and extent of vaporization:

  • Temperature: Higher temperatures increase the kinetic energy of molecules, leading to a higher rate of vaporization.
  • Surface Area: A larger surface area allows more molecules to escape into the gas phase.
  • Pressure: Lower atmospheric pressure can increase the rate of vaporization.
  • Intermolecular Forces: Substances with weaker intermolecular forces vaporize more easily.

Applications of Vaporization[edit]

Vaporization has numerous applications in everyday life and industry:

  • Cooling Systems: Evaporation is used in cooling systems, such as refrigerators and air conditioners, to remove heat from the environment.
  • Distillation: This process uses vaporization to separate components of a mixture based on differences in boiling points.
  • Cooking: Boiling is a common method of cooking food, utilizing the heat from vaporization to cook ingredients.
