Answer 1

Answer:

Both A and R are correct but R is not the correct explanation of A

Explanation:

Desert cooler do not work efficiently during rainy season because

It absorbs the heat in air for evaporation. Wet weather the air is humid so little evaporation. The Air coolers will work in rainy season, but they will not work usefully or effectively. This is because the Humidity of the atmospheric air will be very high, sometimes as high as 95–100%.

Evaporation is a surface phenomenon as

Evaporation is a surface phenomenon because

• Evaporation is a surface phenomenon because, during evaporation, the molecules with higher kinetic energy dissipate into the air from the topmost layer of the liquid so it is a surface phenomenon. ... Therefore, evaporation takes place from the surface but not from the inside
