Why does a puddle of water disappearing?

A puddle of water disappears primarily due to evaporation, where the water molecules gain energy from the surrounding heat and transition into vapor. Additionally, factors like sunlight, wind, and temperature can accelerate this process. Absorption by the ground or surrounding materials can also contribute to the puddle's disappearance. Collectively, these processes lead to the gradual reduction in the puddle's size until it is no longer visible.
