Why does a desert cooler cool better on a hot dry day?
In a desert cooler, the water inside it is made to evaporate. This leads to absorption of energy from the surroundings, thereby cooling the surroundings. Again, we know that evaporation depends on the amount of water vapour present in air (humidity). If the amount of water vapour present in air is less, then evaporation is more. On a hot dry day, the amount of water vapour present in air is less. Thus, water present inside the desert cooler evaporates more, thereby cooling the surroundings more. That is why a desert cooler cools better on a hot dry day.
Why does a desert cooler cool on a hot dry day?
Evaporation requires heat to supply the energy of vaporization. This heat is supplied by the unevaporated water, which must correspondingly cool.
Why does an air cooler cool better on a hot dry day?

How do raptor keep cool?
Velociraptor lived in the Gobi Desert. To deal with the heat, they were mostly noctournal. By sleeping in the shade during the day and being active at night while it was cooler, they could reduce the risk of overheating.
Why might you not see any animals if you went for a walk in a desert during the day?
Many desert animals are not abroad during the heat of the day and only emerge at night when it is cooler.
Is the desert cool?
Some deserts are naturally cool or even bitterly cold. The Patagonian Desert, Atacama Desert and Antarctica are examples of cold deserts. Other deserts are hot during the day but can become quite cool at night.
When do Arctic foxes sleep?
A desert fox, and most all desert animals, sleep during the day, and hunt at night, because it is cooler at night.
Does a ball bounces better on a cool day?
no
Why does a desert cooler cools better on a hot dry day?
How Does it Work?The heart of an evaporative cooling system is the pad where the water evaporates and the air passing through the pads is cooled. A special water distribution system spreads water over the surface of the pad, ensuring a uniform supply of water to keep the entire air contact surface thoroughly wetted. Fans create a negative pressure, causing air to be drawn through the pads. Evaporation results from contact between air and water. A control system operates the water pump and the fan distributes the cool air.The relative humidity is lowest in the afternoon when the temperature is at its highest. And the lower the humidity, the better the evaporative cooling effect. In other words, the cooling effect is best when you need it the most.Source: www.bajarangs.com/whyevaporativecoolers.html
Which area will cool off faster at night the desert or an ocean town?
A desert will cool off much more quickly as there is little humidity or cloud cover that would hold in the heat of the day.
Why is it always hot in a desert?
There are hot deserts and there are cold deserts so it is not always hot in a desert. The Antarctic Desert stays below the freezing mark even in summer. Some deserts are hot during the day but get quite chilly at night.
Are there any dangers in the desert?
A desert.. I think so because most of the animals are sleeping during the day when it's hot out, and they come out at night when it's much cooler. But i am pretty sure that there are some dangerous animals in a desert.
