Expert Answer
Dear vrishtitokas@yahoo.com
Thanks for asking us a question in Ask the Expert section of TopperLearning.com.
In case of multiple questions within a query, please post each question individually and let us know where you are getting stuck so that we would be able to explain things better.
Solution for your first query,
On a hot dry day, the temperature is high and humidity is low. The water takes heat from the hot desert cooler and evaporates. The evaporation of water cools the pads and the circulating water. As a result the incoming air also gets cooled down.
Regards
