Evaporation is a surface phenomenon. In case of pure water any of the molecules of water at surface have the chance of escaping into the air but when salt is added into water some of the ions of salt will come on the surface and thus block some of the surface area which was earlier available for water molecules to escape. Hence chance of water molecules escaping into air becomes less so water with salt evaporates slower than water without salt. This effect is known as elevation in boiling point.

TaigaAdding salt to water raises its boiling point and reduces the rate of evaporation. This is due to the decreased vapor pressure of the saltwater compared to freshwater. The presence of salt particles in the water slows down the movement of water molecules at the surface, leading to a slower evaporation rate.

Does bleach evaporate faster than alcohol?
Yes, bleach typically evaporates slower than alcohol because it has a lower vapor pressure. Alcohol evaporates quickly because it has a higher vapor pressure.
Does the type of water in a pool affect how it evaporates?
Yes, the type of water in a pool can affect how it evaporates. For example, saltwater pools may have slower evaporation rates compared to freshwater pools due to the higher salt content. Additionally, factors such as temperature, humidity, and wind can also influence the rate of evaporation in a pool.

Will water with salt evaporate faster than water without salt?
No. Water with salt evaporates slower than water without salt. The reason, is because water with salt raises the boiling point of water, therefore meaning it requires more heat to evaporate. Water normally evaporates at all temperatures above freezing; the higher the temperate, the faster it evaporates. Plain water will boil at 212 degrees Fahrenheit, whereas a mixture of 2 tablespoons salt to 2 cups of water will cause water to boil at 217 degrees Fahrenheit. The reason is because of an ionic bond caused from the salt. It's harder to break the bond, so more heat is needed which, in the end result, increases the boiling point of water.
How does a liquid evaporates and freezes?
A liquid evaporates when its molecules gain enough energy to overcome the intermolecular forces holding them together, enabling them to escape into the gas phase. On the other hand, freezing occurs when a liquid loses energy, causing its molecules to slow down and arrange themselves into a more structured and orderly solid state.
