Answer:

Ok, first is important that you understand how the heat radiation works.

All the objects that have some heat energy in them, radiate some of that energy in the form of electromagnetic waves.

Particularly, the Sun radiates a lot of energy (at the point that if you step under the sunlight, you can feel on your skin the heat that comes from the sun, this is due to radiation).

Now, suppose that you have a thin coat of water over you, then the material that gets impacted by that radiation will be the water and not you, and then the energy is dissipated (some of the energy goes to your body and some go to the air)

This is one way in which spraying water over themselves helps the elephants to keep them cool.

Another way in which heat can be transferred is by conduction.

When you have a hot object and a cool object, and you put them together (so the objects touch each other), the heat will flow from the hotter object to the cooler object until both objects have the same temperature.

Then if the elephant body temperature is larger than the temperature of the water that the elephant sprays over his body, when the water touches the body some of the heat in the elephant body will be transferred to the coat of water, and in this way, the temperature of the elephant's body decreases.

These are the two ways we wanted to find.
