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 ...
