Exempel på hur man kan använda VAPOUR i en mening

• It is a volatile red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour.
• Cavitation in fluid mechanics and engineering normally refers to the phenomenon in which the static pressure of a liquid reduces to below the liquid's vapour pressure, leading to the formation of small vapor-filled cavities in the liquid.
• Potential evapotranspiration, a measure of the atmospheric demand for water vapour from evaporation and transpiration.
• In physics, a vapor (American English) or vapour (Commonwealth English; see spelling differences) is a substance in the gas phase at a temperature lower than its critical temperature, which means that the vapor can be condensed to a liquid by increasing the pressure on it without reducing the temperature of the vapor.
• Boiling or ebullition is the rapid phase transition from liquid to gas or vapour; the reverse of boiling is condensation.
• This happens because when an azeotrope is boiled, the vapour has the same proportions of constituents as the unboiled mixture.
• A diverse range of synthetic techniques, such as the ceramic method and chemical vapour depostion, make solid-state materials.
• In addition to the radio transmitters sending telemetry information back to Earth, the spacecraft released a sodium vapour cloud so the spacecraft's movement could be visually observed.
• Bubbles form when water accelerates around sharp corners and the pressure drops below the vapour pressure.
• This includes water in gaseous, liquid and frozen forms as soil moisture, groundwater and permafrost in the Earth's crust (to a depth of 2 km); oceans and seas, lakes, rivers and streams, wetlands, glaciers, ice and snow cover on Earth's surface; vapour, droplets and crystals in the air; and part of living plants, animals and unicellular organisms of the biosphere.
• A poppet valve (also sometimes called mushroom valve) is a valve typically used to control the timing and quantity of petrol (gas) or vapour flow into or out of an engine, but with many other applications.
• Ancient Greek philosopher Aristotle observed in his work Meteorology that "salt water, when it turns into vapour, becomes sweet and the vapour does not form salt water again when it condenses," and that a fine wax vessel would hold potable water after being submerged long enough in seawater, having acted as a membrane to filter the salt.
• Cellophane is highly permeable to water vapour, but may be coated with nitrocellulose lacquer to prevent this.
• A mushroom cloud is a distinctive mushroom-shaped flammagenitus cloud of debris, smoke, and usually condensed water vapour resulting from a large explosion.
• In a distillation column, the reflux or condensed vapour runs down the column, covering the surfaces of the rings, while vapour from the reboiler goes up the column.
• The synthesis of iodoform was first described by Georges-Simon Serullas in 1822, by reactions of iodine vapour with steam over red-hot coals, and also by reaction of potassium with ethanolic iodine in the presence of water; and at much the same time independently by John Thomas Cooper.
• A loop in the pipes takes the vapour from the stills to the worm tubs, which causes some of the alcohol to condense before it reaches the cooler.
• Since colder air can hold less water vapour, moisture condenses to form clouds and precipitates as rain or snow on the mountain's upwind slopes.
• Conversely, in oxygenic photosynthetic organisms such as most land plants, uptake of carbon dioxide and release of both oxygen and water vapour are the main gas-exchange processes occurring during the day.
• During distillation, this vapour travels up the swan neck at the top of the pot still and down the lyne arm, after which it travels through the condenser (also known as the worm), where it is cooled to yield a distillate with a higher concentration of alcohol than the original liquid.
