The rate of evaporation increases with increase in temperature. So, near the anghiti or heater, the rate of evaporation will be higher and the uniform will dry up quickly. https://www.tiwariacademy.com/ncert-solutions/class-6/science/chapter-14/

It is due to condensation of water vapours present in air. Air contains water in the form of vapours, when it comes in contact of cool water bottle, it gets condense and converted into water droplets. https://www.tiwariacademy.com/ncert-solutions/class-6/science/chapter-14/

When we breathe out, moist air comes out (along with energy and carbon dioxide) which make the glasses wet (as water vapours get condense on glass). https://www.tiwariacademy.com/ncert-solutions/class-6/science/chapter-14/

Evaporation takes place from all open surfaces of water. As a result, water vapour gets continuously added to air. As these vapours go higher from the surface of the earth, it gets cooler and cooler. At sufficient heights, the air becomes so cool that the water vapour present in it condenses to formRead more
Evaporation takes place from all open surfaces of water. As a result, water vapour gets continuously added to air. As these vapours go higher from the surface of the earth, it gets cooler and cooler. At sufficient heights, the air becomes so cool that the water vapour present in it condenses to form tiny drops of water called droplets. It is these tiny droplets that remain floating in air and appear to us as clouds.
If it does not rain in a region for a year or more. The soil continues to lose water by evaporation and transpiration. Since it is not being brought back by rain, the soil becomes dry.

Suppose you want to dry your school uniform quickly. Would spreading it near an anghiti or heater help? If yes, how?
