Evaporation ponds are used. Evaporation ponds are artificial ponds with very large surface area that are designed to efficiently evaporate water by sunlight and exposure to the ambient temperature.

Sea water is a mixture of water and salt , by the phenomenon of evaporisation water of this mixture is evaporated and we get salt only .

The wet paint is dried out because liquid portion in paint is evaporated . Although evaporisation is also a type of vaporisation .

Splashes dry up at the edges of puddle , because of evaporisation as high energy molecules of water escape from water .

Evaporation or perspiration cools our body, it is true . Because molecules of sweat in perspiration , having higher kinetic energy and it goes out in the form of sweat, hence the average kinetic energy (internal energy) of molecules in sweat decreases, therefore, its temperature gets down and we feel cooler .

Clothes are dried by evaporation due to heat from sunlight . In a line , clothes get sunlight for whole day , and due to heat from sun, rate of evaporation increases and clothes dry quickly .

Our floor get wet due to mopping , and after some time water droplets are evaporated and floor become dry .

Evaporation is the final step of a water cycling driving small turbines before it is fed back into the primary pool. Water vapours are moving in the pipe at high speed under pressure exposed to turbine; which makes turbine rotate; left water vapour again condenses and go back in liquid state.

A puddle on the road dries out after some time due to evaporation, not due to fermentation . 

When we dry our hair , evaporisation takes place , as water droplets in hair are evaporated by air . The given statement is true .
