The earthenware is porous.Through these microscopic pores,water comes out very very slowly and when the water from outside surface of the ware gets vaporised it absorbs latent heat from the ware itself and thereby makes the ware and the water inside cooler.
water keeps cool by putting icepacks beside it.

Mulch keeps the roots of plants cool. Also plants give off water from their leaves. This is called transpiration.
The process of transpiration keep plants cool. Water is evaporated from plants.

Water or coolant keeps the engine cool . -Some engines are air cooled.
The fluid that keeps the body cool is sweat.
it keeps cool in the day maybe.
Oil is not a coolant, it is a lubricant, but it keeps the engine lubricated to prevent friction, which reduces heat and makes is run cooler. Water in the radiator, and the radiator fan, is what keeps the engine cool.
during sunny days the roof of the house gets hot by sprinkling water on it this help to escape heat from the roof in the form of water vapour & the water gives cooling effect
