The energy conversion that takes place in an evaporative cooler is: a. thermal energy to chemical energy b. thermal energy to heat c. cooling of thermal energy d. heat energy to mechanical energy

C. Cooling of thermal energy

Explanation:

In evaporative cooling liquid water convert into vapor by using thermal energy. In this out side air is used to evaporate the water.

Hot air enters from outside and this hot air gets contact with wet matrix. In wet matrix temperature of air will reduce and temperature of water will increases. After wet matrix heat transfer take place between air and water. After that by using force convection air pushed out and produce cooling.
