Evaporation - Wikipedia
WEBEvaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. A high concentration of the evaporating substance in the surrounding gas significantly slows down evaporation, such as when humidity affects rate of …
Evaporation - Simple English Wikipedia, the free encyclopedia
WEBEvaporation is when a liquid becomes a gas without forming bubbles inside the liquid volume. If bubbles are formed we are talking instead about "boiling". For example, water left in a bowl will slowly disappear. The water evaporates into water vapor, the gas phase of water. The water vapor mixes with the air.
Enthalpy of vaporization - Wikipedia
WEBIn thermodynamics, the enthalpy of vaporization (symbol ∆H vap), also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy that must be added to a liquid substance to transform a quantity of that substance into a gas.

Evaporation | Definition, Water Cycle, & Facts | Britannica
WEBEvaporation, process by which an element or compound transitions from its liquid state to its gaseous state below its boiling temperature. It is also how liquid water enters the atmosphere as water vapor, which is an important part of energy exchange that affects weather and climate.
Vacuum evaporation - Wikipedia
WEBVacuum evaporation is the process of causing the pressure in a liquid-filled container to be reduced below the vapor pressure of the liquid, causing the liquid to evaporate at a lower temperature than normal. Although the process can be applied to any type of liquid at any vapor pressure, it is generally used to describe the boiling of water by ...
The Process of Evaporation - National Geographic Society
WEBOct 19, 2023 · Evaporation happens when a liquid substance becomes a gas. When water is heated, it e vaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Evaporation is a very important part of the water cycle. Heat from the sun, or solar energy, powers the …
Evaporation and the Water Cycle | U.S. Geological Survey - USGS.gov
WEBJun 8, 2019 · Evaporation is the process that changes liquid water to gaseous water (water vapor). Water moves from the Earth’s surface to the atmosphere via evaporation. Evaporation occurs when energy (heat) forces the bonds that hold water molecules together to break. When you’re boiling water on the stove, you’re adding heat to liquid water.
13.7: Evaporation - Chemistry LibreTexts
WEBSep 21, 2022 · Summary. Evaporation is the conversion of a liquid to its vapor below the boiling temperature of the liquid. Condensation is the change of state from a gas to a liquid. As the temperature increases, the rate of evaporation increases.
Evaporation | Encyclopedia.com
WEBMay 17, 2018 · Evaporation is the movement of a substance from its liquid to its vapor phase. (Movement directly from solid to vapor phase is called sublimation.) It is commonly used to concentrate solutions of nonvolatile solutes and volatile solvents.
