1.when tea is poured into a saucer when it is very hot it is exposed to a large area n causes evaporation n the tea becomes cool...
2.In summer seasons the water gets cool in a earthen pot because it has fine pores in it through which water seeps out gets evaporated using the heat of water in earthen pot n causes cooling effect.......
3.when we sweat n sit under a fan we feel cool because of the same principle.....
4. doctors advice patients with fever to keep a wet cloth on their fore head because of the same principle temp. cools down......
5. a wet khus khus screen hung at the door of the room keeps the room cool because when the water in wet khus khus screen evaporates using the heat of the air entering the room and makes the air cool and this cool air enter's the room making it cool.....
Some key points are 1) Evaporation takes internal energy while for boiling we have to provide external energy or we have to reduce the pressure. 2) As Evaporation takes internal energy therefore evaporation results in cooling while this is not observed in boiling. 3) Evaporation can occur below saturated temperature while Boiling occurs only at and above saturated temperature. 4) Evaporation occurs at only at the liquid/vapor interface while Boiling may occur at a solid/liquid interface. 5) Vapor bubbles are formed in Boiling while in Evaporation there are no bubble formation and no bubble motion. 6) There are different regimes of boiling (like nucleate boiling, transition boiling, film boiling etc.) while these regimes are not present in Evaporation. 7) Rate at which a substance changes from liquid to vapor through Evaporation is much slower than when Boiling. 8) Example of Evaporation are Water in a lake at 20°C, evaporates to air at 20°C and 60 percent relative humidity since the saturation pressure of water at 20°C is 2.34 kPa, and the vapor pressure of air at 20°C and 60 percent relative humidity is 1.4 kPa. Other examples of evaporation are the drying of clothes, fruits, and vegetables; the evaporation of sweat to cool the human body; and the rejection of waste heat in wet cooling towers. i am hoping that the above comparison will give you the clear picture about the evaporation and boiling.

Examples: rubbing alcohol, beer, liquid detergent, vinegar, gasoline.
Evaporation is a phase transition from liquid to gas that occurs at the surface of a liquid. It is a spontaneous process driven by an increase in temperature and the kinetic energy of molecules. Evaporation causes cooling of the remaining liquid due to the energy required to break intermolecular bonds. Factors influencing the rate of evaporation include temperature, surface area, humidity, and air movement. Evaporation plays a crucial role in the water cycle by redistributing water vapor in the atmosphere.
Sweating: When sweat evaporates from your skin, it cools you down by removing heat from your body. Wet towel: Placing a wet towel on your forehead helps cool you down as the water evaporates and takes heat with it. Puddle drying: Puddles of water evaporating on a hot day can create a cooling effect in the surrounding area. Misting fans: Spraying water into the air to create a mist that evaporates can help lower the temperature in a given space. Sprinkler system: Watering the ground on a hot day can lead to evaporation, which can help cool the surrounding area.

Some key points are 1) Evaporation takes internal energy while for boiling we have to provide external energy or we have to reduce the pressure. 2) As Evaporation takes internal energy therefore evaporation results in cooling while this is not observed in boiling. 3) Evaporation occurs below saturated temperature while Boiling occurs at and above saturated temperature. 4) Evaporation occurs at liquid-vapor interface while Boiling occurs at solid liquid interface. 5) Vapor bubbles are formed in Boiling while in Evaporation there are no bubble formation and no bubble motion. 6) There are different regimes of boiling (like nucleate boiling, transition boiling, film boiling etc.) while these regimes are not present in Evaporation. 7) Rate of Evaporation is much slower than the Boiling. 8) Example of Evaporation are Water in a lake at 20°C, evaporates to air at 20°C and 60 percent relative humidity since the saturation pressure of water at 20°C is 2.34 kPa, and the vapor pressure of air at 20°C and 60 percent relative humidity is 1.4 kPa. Other examples of evaporation are the drying of clothes, fruits, and vegetables; the evaporation of sweat to cool the human body; and the rejection of waste heat in wet cooling towers. i am hoping that the above comparison will give you the clear picture about the evaporation and boiling.
