vapori-, vapor-, vapo-

(Latin: steam, mist, very small drops of water)

anesthetic vaporizer (s) (noun), anesthetic vaporizers (pl)
A device for the gaseous state of a process that prevents pain, preferably at a constant temperature, into a carrier gas, usually oxygen, oxygen plus nitrous oxide, or air: An anesthetic vaporizer is a piece of equipment that is generally attached to an anesthetic machine which delivers a given concentration of a volatile anesthetic agent as it is needed by the medical staff for surgery, etc.
atmidometric (adjective), more atmidometric, most atmidometric
A reference to the rate at which water is decreased measured; usually, into the atmosphere by a special device: "An atmidometric instrument is used to determine the amount of evaporation of a moist surface that takes place in a given time."
devaporation (s) (noun), devaporations (pl)
The process of changing vapor into water: "When rain is being formed in the atmosphere, that's when devaporation is taking place."
evaporability (s) (noun), evaporabilities (pl)
That which can be diffused or suspended in the air: "The evaporability of the chemicals were being tested by the chemist."
evaporable (adjective), more evaporable, most evaporable
Descriptive of that which can change or cause to change from a liquid or solid state to a mist or steam: "There are certain evaporable liquids or fluids that can be turned into a more concentrated residue which remains after the evaporation process has taken place."
evaporate (verb), evaporates; evaporated; evaporating
1. To lose, or cause to lose, liquid by changing water into steam and leaving a more concentrated residue: "As something evaporates, it changes a liquid into a mist or fumes which is usually done by heating to just below its boiling point, or to change from a liquid to a mist in this way."

"The solution was evaporated to dryness."

3. To remove liquid from something, usually by heating, to produce a more concentrated or solid substance: "Bruce evaporated the oil by heating it enough to evaporate any remaining moisture."
4. To disappear gradually, or to fade away to nothing: "The militancy of the group had evaporated since their defeat by government forces."

"To evaporate something; such as, a metal film on a surface through the condensation of a gaseous or a steam substance."

evaporated milk (s) (noun), evaporated milks (pl)
A white liquid that comes from cows, goats, and sheep which has been thickened, or concentrated, by removing some of the water by reducing it: "Evaporated milk consists of unsweetened milk that is made by evaporating some of the water from the whole milk."

"Evaporated milk is labeled as enriched whole milk that is concentrated, sterilized, and often canned."

evaporation (s) (noun), evaporations (pl)
A process in which something is changed from a liquid to a gaseous substance without its temperature reaching boiling point: "Evaporation consists of a fluid that has been changed into a vapor; usually, by means of the slow process that occurs below the boiling point of the liquid."
evaporation pond (s) (noun), evaporation ponds (pl)
A containment pond designed to hold liquid wastes and to concentrate the waste through a process of decreasing the amount of water: "The evaporation pond reduces the amount of water so the waste material is more visible and easier to dispose of."
evaporation rate (s) (noun), evaporation rates (pl)
The rate at which a particular substance will be changed into a gas when compared to the rate of a known substance; such as, ethyl ether: "The evaporation rate is especially useful for health and fire-hazard considerations."
evaporative (adjective), more evaporative, most evaporative
Any process in which a liquid is converted into its gaseous phase by the addition of heat to the liquid: "An example is the evaporative condenser that is an apparatus that utilizes the evaporation of water by air at the condenser surface as a means of dissipating heat."
evaporative cooler (s) (noun), evaporative coolers (pl)
An air-cooling unit that turns ambient air into moist, cooler air: "The evaporative cooler in Bill's apartment made things more comfortable by saturating the hot summer air with water vapor."
evaporator (s) (noun), evaporators (pl)
The component or element of a refrigeration system in which the refrigerant withdraws heat energy: "The evaporator changes heat from a liquid to a gas making the device cooler."

" An evaporator involves any process in which evaporation occurs; especially, one designed to concentrate a solution."

evaporimeter, evaporometer (s) (noun); evaporimeters, evaporometers (pl)
An instrument for measuring the rate of the process of a liquid that is converting a gaseous state of water into the atmosphere: "An evaporimeter measures the rate at which water evaporates."
evapotranspiration (s) (noun), evapotranspirations (pl)
The total loss of water from a particular area, equal to the sum of the amount of water lost by the removal of moisture from the soil, and other surfaces, and the amount lost by the emission of water from plants: "Evapotranspiration involves the combined removal of water from surfaces by the loss of moisture and from the outward passage of fine particles of water along with carbon dioxide from plants."

"Evapotranspirations are the combined removals of water from surfaces by evaporation and from plants by transpiration."
