Evaporate definition, to change from a liquid or solid state into vapor; pass off in vapor. See more.

Chem4Kids.com: Matter: Evaporation

Evaporation happens when atoms or molecules escape from the liquid and turn into a vapor. Not all of the molecules in a liquid have the same energy. When you have a puddle of water (H 2 O) on a windy day, the wind can cause an increased rate of evaporation even when it is cold out.

Difference Between Boiling and Evaporation (with Boiling .

Evaporation Line Pregnancy Test: Positive or Negative?

Dec 06, 2018 · Evaporation lines are common and can occur with any pregnancy test. An evaporation line is a line that appears in the results window of a pregnancy test as the urine dries.

Quantifying the evaporation amounts of 75 high-elevation .

Lake evaporation can influence basin-wide hydrological cycles and is an important factor in loss of water resources in endorheic lakes of the Tibetan Plateau. Because of the scarcity of data, published lake evaporation values are inconsistent, and their spatial distribution has never been reported. Presenting a plausible hypothesis of energy balance during the ice-free seasons, we explored the .

EVAPORATION | definition in the Cambridge English Dictionary

evaporation meaning: 1. the process of a liquid changing to a gas, especially by heating: 2. the fact of something.. Learn more.

Evaporation - an overview | ScienceDirect Topics

Evaporation is the physical separation of a liquid from a dissolved or suspended solid by applying energy to make the liquid volatile. Evaporation may be used to isolate the hazardous material in one of the two phases, simplifying subsequent treatment if the hazardous waste is volatilized; this process is usually called stripping. Evaporation .

Evaporation | Encyclopedia.com

Evaporation. Evaporation is a process that is commonly used to concentrate an aqueous solution of nonvolatile solutes and a volatile solvent. In evaporation, a portion of the solvent is vaporized or boiled away, leaving a thick liquid or solid precipitate as the final product.

Evaporation Rates, Condensation Rates, and Relative .

Meanwhile, temperature controls evaporation rates (higher temperatures yield higher evaporation rates), so relative humidity depends on dew point (which reflects the amount of water vapor present) and temperature. I should point out, however, that we can't just substitute dew point and temperature into the equation for relative humidity above .

Evaporation | National Geographic Society

Aug 08, 2019 · Evaporation happens when a liquid turns into a gas. It can be easily visualized when rain puddles "disappear" on a hot day or when wet clothes dry in the sun. In these examples, the liquid water is not actually vanishing—it is evaporating into a gas, called water vapor. Evaporation happens on a .

evaporation - Dictionary Definition : Vocabulary.com

evaporation: 1 n the process of becoming a vapor Synonyms: vapor, vaporisation, vaporization, vapour Types: show 4 types. hide 4 types. boiling the application of heat to change something from a liquid to a gas clouding, clouding up the process whereby water particles become visible in the sky smoke, smoking a hot vapor containing .

What is Evaporation? - Definition, Process & Examples with .

Evaporation can generally be defined as a process by which a liquid or solid is transformed into vapour. When you spray perfume on your body, your body feels slightly cooler. The same goes for acetone and water. This is an effect of evaporation or the change of matter from its liquid state to its vapour state.

Evaporation definition and meaning | Collins English .

Evaporation definition: Evaporation is when a liquid changes to a vapor, caused by an increase in temperature. | Meaning, pronunciation, translations and examples

Evaporation | Encyclopedia.com

Evaporation is a process that is commonly used to concentrate an aqueous solution of nonvolatile solutes and a volatile solvent. In evaporation, a portion of the solvent is vaporized or boiled away, leaving a thick liquid or solid precipitate as the final product. The vapor is condensed to recover the solvent or it can simply be discarded.

The Differences Between Vaporization & Evaporation | Sciencing

The difference between vaporization and evaporation is that vaporization is a transitional phase of an element as it changes from a liquid into the gas at a point greater than the boiling point. Evaporation is the same phase transition, but it takes place below the boiling temperature.

evaporation | Origin and meaning of evaporation by Online .

evaporation (n.) late 14c., from Old French évaporation and directly from Latin evaporationem (nominative evaporatio ), noun of action from past participle stem of evaporare "disperse in vapor or steam," from assimilated form of ex "out, out of" (see ex- ) + vapor "steam" (see vapor ).

evaporation | Definition & Facts | Britannica

Evaporation, the process by which an element or compound transitions from its liquid state to its gaseous state below the temperature at which it boils; in particular, the process by which liquid water enters the atmosphere as water vapour. Evaporation, mostly from the sea and from vegetation, replenishes the humidity of the air.

Evaporation - Wikipedia

Evaporation from Water Surface - Engineering ToolBox

The evaporation from the surface can be calculated as. g s = (34.5 kg/m 2 h) (1000 m 2) ((0.014659 kg/kg) - (0.0098kg/kg)) / 3600 = 0.047 kg/s. The evaporation heat (enthalpy) of water at temperature at 20 o C is 2454 kJ/kg. The heat supply required to maintain the temperature of the water in the swimming pool can be calculated as. q = (2454 kJ .

Difference Between Evaporation and Vaporization

Aug 05, 2015 · Evaporation occurs when the vapor pressure is below external pressure. Vaporization includes state change from liquid to gas when the vapor pressure is both below or equal to the pressure from the surroundings. Location of Vaporizing Molecules. In evaporation, the molecules that vaporize are from the liquid surface.
