A fan helps to dry clothes faster by increasing the air circulation around them. As the fan blows air, it removes the moisture from the clothes more quickly. This speeds up evaporation, where the water in the clothes changes into ...
Water reaches the clouds through the process of evaporation. When the sun heats up water from oceans, lakes, and rivers, it turns into water vapor and rises into the air. As the water vapor rises, it cools down and condenses ...
Rain cools the air because when raindrops fall, they absorb heat from the surrounding air. The process of evaporation, which happens as the rain drops, helps in cooling the air as the water absorbs energy to change from liquid to ...
In summer, we sprinkle water on the ground to cool the air around us. When water evaporates from the surface, it absorbs heat from the surroundings, which helps lower the temperature. This process is called evaporation, and it cools the ...
A pot-in-pot cooler keeps things cool through the process of evaporation. It consists of two pots, one smaller pot inside a larger pot, with a wet cloth placed between them. When water evaporates from the cloth, it absorbs heat, cooling ...
The process that turns liquid water into ice is called freezing. When water is cooled to a temperature of 0°C or below, its molecules slow down and arrange themselves into a solid structure, forming ice. This happens because the temperature ...
Over time, water in an open container will gradually disappear due to evaporation. When the water is exposed to air, its molecules at the surface gain enough energy to turn into water vapor and rise into the air. This process ...
Dew is seen in the morning because, during the night, the ground cools down. As the temperature drops, the water vapor in the air condenses into tiny droplets when it comes in contact with cooler surfaces like grass, leaves, or ...
We feel cooler when we sweat because of the process of evaporation. When sweat evaporates from our skin, it absorbs heat from our body, which helps lower our body temperature. This cooling effect is especially helpful on hot days, as ...
