About this deal

Hi, I'm Salty, Drippy's saline counterpart! Did you know that one way to produce table salt is to evaporate saline water in evaporation ponds, a technique used by people for thousands of years? People make use of evaporation Before long, the water level drops. Even after we take the heat away, the liquid continues to evaporate, leaving crystals of salt behind.

Sometimes, near the top of the glass, the water particles will be going fast enough to escape into the air. When the molecules in a liquid are heated, they move faster. This makes them full of energy and so the particles collide with each other, and eventually they become so far apart that they become a gas. There are two key differences between evaporation and boiling. The first difference is where the change of state occurs. Evaporation takes place only at the surface of a liquid, whereas boiling may occur throughout the liquid. In boiling, the change of state takes place at any point in the liquid where bubbles form; the bubbles then rise and break at the surface of the liquid. The second difference between evaporation and boiling concerns temperature. Evaporation can take place at any temperature. For example, a puddle of water will evaporate on a cold day, though the rate of evaporation will be slower than it would be on a warm day. In contrast, boiling only occurs at the boiling point of the liquid. ApplicationsThis article needs additional citations for verification.

Evaporation is a process by which a substance changes from a liquid state to a gaseous state at temperatures below the boiling point of the liquid. In nature, evaporation—especially from the oceans—plays a key role in the water cycle by moving water from its liquid state on Earth’s surface to the atmosphere as water vapor. The rate of evaporation depends on the temperature difference between the surface of the liquid and the air. The greater the difference in temperature, the faster evaporation occurs. How Evaporation Occurs

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. [1] High concentration of the evaporating substance in the surrounding gas significantly slows down evaporation, such as when humidity affects rate of evaporation of water. [2] When the molecules of the liquid collide, they transfer energy to each other based on how they collide. When a molecule near the surface absorbs enough energy to overcome the vapor pressure, it will escape and enter the surrounding air as a gas. [3] When evaporation occurs, the energy removed from the vaporized liquid will reduce the temperature of the liquid, resulting in evaporative cooling. [4]Rather than heating the evaporating basin directly with a Bunsen burner, it is often better to warm it gently and slowly over a beaker of boiling water. One way to produce table salt is to evaporate saline water in evaporation ponds, a technique used by people for thousands of years. Humidity of the surroundings: The greater the humidity of the atmosphere surrounding the water, the slower the rate of evaporation. increase the moisture content in the air - may increase the condensation and damage of the building constructions for indoor pools

As we've just seen, the rate of evaporation can be increased by heating the solution. So, if I left some of the salt solution on a sunny windowsill, the heat from the sun would warm up the water and slowly it would evaporate into the air.

The drying force of air depends on the air moisture holding capacity and the water surface to air evaporation capacity. Note! - during operation time the activity in a swimming pool may increase the evaporation of water and the required heat supply dramatically. Industrial applications include many printing and coating processes; recovering salts from solutions; and drying a variety of materials such as lumber, paper, cloth and chemicals. where P 1, P 2 are the vapor pressures at temperatures T 1, T 2 respectively, Δ H vap is the enthalpy of vaporization, and R is the universal gas constant. The rate of evaporation in an open system is related to the vapor pressure found in a closed system. If a liquid is heated, when the vapor pressure reaches the ambient pressure the liquid will boil. 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

If evaporation takes place in an enclosed area, the escaping molecules accumulate as a vapor above the liquid. Many of the molecules return to the liquid, with returning molecules becoming more frequent as the density and pressure of the vapor increases. When the process of escape and return reaches an equilibrium, [5] the vapor is said to be "saturated", and no further change in either vapor pressure and density or liquid temperature will occur. For a system consisting of vapor and liquid of a pure substance, this equilibrium state is directly related to the vapor pressure of the substance, as given by the Clausius–Clapeyron relation: Evaporative coolers, which can significantly cool a building by simply blowing dry air over a filter saturated with water.Moist and humid air - psychrometric charts, Mollier diagrams, air-condition temperatures and absolute and relative humidity and moisture content. After a couple of days, the solution I left on the windowsill has also evaporated. The energy from the sun has warmed the solution, speeding up evaporation. Like before, the water has turned into gas in the air and the salt has been left behind. Kotaro Ohashi (18 May 2020).
