A desert cooler given comfort due to cooling caused by evaporation of ...
Explanation:
A desert cooler works effectively in hot and dry weather because of the following reasons:
1. Evaporation: The cooling effect in a desert cooler is due to the evaporation of water. In hot and dry weather, the air is dry, and there is low humidity. Hence, the evaporation of water is more effective, leading to a better cooling effect.
2. Humidity: In humid weather, the air already has a high content of moisture, which reduces the effectiveness of the cooling effect. So, in humid weather, the desert cooler will not work efficiently.
3. Rainy weather: In rainy weather, the air already has a high level of moisture, which means the air is already saturated with moisture. Hence, the evaporation of water will not be as effective, and the cooling effect will not be significant.
4. Sunny weather: A hot and sunny day is ideal for a desert cooler as it ensures that the air is hot and dry, which creates a perfect environment for the cooling effect to take place.
Therefore, it can be concluded that a desert cooler works more effectively in hot and dry weather as the evaporation of water is more effective in such conditions.
