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 ...
Humidity is the amount of water vapor present in the air. It can be high or low depending on how much moisture the air contains. When the humidity is high, the air feels moist and sticky, while low humidity makes ...
To speed up evaporation, we can increase the temperature, increase the surface area, and ensure good air circulation. Higher temperatures give the molecules more energy to escape into the air faster. Spreading the liquid out over a larger surface area ...
The process when ice turns directly into vapor is called sublimation. During sublimation, the ice absorbs heat and changes directly from a solid to a gas without becoming liquid first. This usually happens under certain conditions, such as low pressure ...
Raindrops form when water vapor in the air cools and condenses to form tiny water droplets. These droplets cluster together in clouds, growing larger as more water vapor condenses onto them. When the droplets become too heavy to stay in ...
Condensation plays a key role in forming clouds. When warm air rises, it cools as it reaches higher altitudes. As the air cools, the water vapor in it condenses into tiny water droplets or ice crystals, forming clouds. These droplets ...
Clothes dry faster in sunlight because sunlight provides heat, which increases the energy of water molecules in the clothes. This heat speeds up the evaporation process, causing the water to turn into vapor more quickly. Additionally, the warmth of the ...
Evaporation causes cooling because, during the process, the fastest-moving particles of a liquid escape into the air. These particles carry away energy, or heat, with them. As a result, the remaining liquid has less energy, which lowers its temperature. This ...
Water vapor is the gaseous form of water that is present in the air. It is created when water evaporates from sources like lakes, rivers, and oceans, or when it is released through activities like boiling water. Water vapor is ...
