When evaporation occurs then than the liquid (mostly water) absorbs all the heat from the surroundings and take it with it and we feel cool. evaporation causes cooling effect because the heat energy is abosorbed by surrounding particles.

Evaporation causes cooling because during evaporation the particle of the liqued absord energy from the surroundings to regain the energy lost during evaporation. the absorbtion of heat from the surrounding makes the surrounding  cool.

Evaporation does not cause heating. In fact, evaporation is a cooling process. This can be explained through the following points:

Explanation:
- Evaporation is the process by which a liquid changes into a gas or vapor by gaining energy from its surroundings.
- During evaporation, the more energetic molecules of the liquid escape into the atmosphere, leaving behind the less energetic ones.
- This leads to a decrease in the temperature of the remaining liquid as the average kinetic energy of its molecules decreases.
- This decrease in temperature is the reason why we feel cool when we step out of a swimming pool or take a shower.
- The energy that is absorbed during evaporation is called latent heat, which is used to break the intermolecular bonds between the molecules of the liquid.
- This energy is not available to increase the temperature of the liquid, but is instead used to change its state from liquid to gas.

Conclusion:
Therefore, it can be concluded that evaporation is a cooling process that leads to a decrease in temperature, and not a heating process as mentioned in option 'A'.
