9. Why does a wet khus-khus screen hung at the door keepthe room cool? |
|
Answer» Awet khus khus screen hung at the door keeps the room cool. ... I have written answer as " Awet khus khus keeps the room coolifhung at the doorbecause the water particles inkhus khusgains energy from the surrounding to evoporate and thus leaves the surroundingcool." A khus khus has a ability to pass air from itself, and when air passes from wet khus khus, this creates a cooling effect. This wet khus khus also show evaporation, and evaporation is an endothermic process means it absorbs energy from surrounding and gives cooling effect. |
