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 ...
