Why does a desert coolar cool better on hot dry day |
|
Answer» A desert cooler cools better on a hot dry day because on a hot dry day temperature is high and humidity is less which helps in better evaporation. Due to the higher rate of evaporation it gives better cooling effect. A desert cooler cools better on a hot dry day because with increase in temperature the rate of evaporation also increases and thus the water particles in the cooler get enough kinetic energy that they escape.. This decreases the overall kinetic energy of the system and thus creating a cool sensation |
