yes
A film of oil at the surface reduce evaporation.
kerosine oil, water, alcohol, petrol...:)
Evaporation.
Evaporation or transpiration (water from vegetation into water vapor) or evapostranspiration (combination of evaporation and transpiration)
An oil reduce evaporation.
yes
A film of oil at the surface reduce evaporation.
this is because it does not decompose by heating
After the evaporation of a salted water salt remain as a solid residue.
A bit of oil on the surface reduce water evaporation.
it increases the evaporation water.

It is more simple to use a separation funnel.
Oil varies considerably in density. Some oil is so thick that it sinks in water. However, it is very uncommon for an oil well to produce very heavy oil. A light oil will have higher rates of evaporation, which means that some of the oil will be lost due to evaporation when it is on the surface. For evaporation, the density or really the composition of the oil is an important factor. Water temperature, air temperature, hours of sunlight, and wave action are additional factors. Loss by evaporation was considerably higher in the BP oil spill than in the Alaskan oil spill (Exxon-Valdez spill). Note that the Alaskan spill, the oil was low density. BP used controlled burns to destroy some of the oil. If the oil was heavier and there was more wave action, this might not have been possible.
1. Separation of table salt from ocean water by evaporation of water; sodium chloride remain as a crystallized solid.2. Separation of oil from water: two phases are formed. The oil from the surface can be separated and collected with the help of a separation funnel.
water rises into the atmosphere in the process of evaporation
