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. The particles are really whizzing about in the water, and they’re escaping into the air, or evaporating, faster than ever. Gusarov, A. V.; Smurov, I. (2002).

Evaporation is not the only process by which a substance can change from a liquid to a gaseous state. The same change can occur through boiling. As a liquid is heated, its molecules absorb heat energy and move faster, as occurs in evaporation. In boiling, however, bubbles of vapor form within the liquid and rise to the surface. The temperature at which this occurs is known as the boiling point of the liquid. Temperature: The greater the temperature of the liquid and its surroundings, the faster the rate of evaporation.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 Note! The units for Θ don't match since the this is an empirical equation - a result of experience and experiments. Required Heat Supply One way to produce table salt is to evaporate saline water in evaporation ponds, a technique used by people for thousands of years.

Hey, I'm Drippy! Did you know that on a global scale, the amount of water evaporating is about the same as the amount of water precipitating? Evaporation drives the water cycle Online calculator, figures and tables with melting points of ice to water at pressures ranging from 0 to 29000 psia (0 to 2000 bara). Temperature given as °C, °F, K and °R.

Concentration of the substance evaporating in the air If the air already has a high concentration of the substance evaporating, then the given substance will evaporate more slowly. Flow rate of air This is in part related to the concentration points above. If "fresh" air (i.e., air which is neither already saturated with the substance nor with other substances) is moving over the substance all the time, then the concentration of the substance in the air is less likely to go up with time, thus encouraging faster evaporation. This is the result of the boundary layer at the evaporation surface decreasing with flow velocity, decreasing the diffusion distance in the stagnant layer. The amount of minerals dissolved in the liquid Inter-molecular forces The stronger the forces keeping the molecules together in the liquid state, the more energy one must get to escape. This is characterized by the enthalpy of vaporization. Pressure Evaporation happens faster if there is less exertion on the surface keeping the molecules from launching themselves. Surface area A substance that has a larger surface area will evaporate faster, as there are more surface molecules per unit of volume that are potentially able to escape. Temperature of the substance the higher the temperature of the substance the greater the kinetic energy of the molecules at its surface and therefore the faster the rate of their evaporation. Liquid with high boiling points (those that boil at very high temperatures) tend to evaporate more slowly than those with lower boiling temperatures.

identify the part played by evaporation and condensation in the water cycle and associate the rate of evaporation with temperature.The Mollier diagram is a graphic representation of the relationship between air temperature, moisture content and enthalpy - and is a basic design tool for building engineers and designers. When the temperature of the liquid (water, in this case) is increased, it results in an increase in the kinetic energy of the individual molecules that constitute the liquid. This increase in energy makes it easier for the liquid molecules to overcome the intermolecular forces of attraction (that holds the liquid together) and escape into the atmosphere as a gas. It can be noted that the temperature of the surrounding can also contribute towards faster evaporation since hot environments can transfer their heat to the liquid. Surface Area Occupied by the Liquid
