. Why does a desert cooler cools better on a hot dry day
- On a hot dry day the water content in the air is comparatively less so it makes the rate of evaporation faster.
- The water inside the cooler will evaporate more easily and because evaporation leads to the cooling of the surrounding it cools better.
- On humid days the water content in the air is comparatively more so the rate of evaporation is slower and due to this a desert cooler cools better on a hot dry day.
Rate of evaporation increases on a hot dry day so a desert cooler cools faster.
