When does water vapor cools and returns to a liquid?

Water vapor cools and returns to a liquid during a process called condensation. This typically occurs when warm, moist air rises and cools, often when it comes into contact with cooler surfaces or when it reaches higher altitudes where temperatures drop. As the air cools, the water vapor loses energy and transitions back into liquid form, forming clouds or dew. This process is a crucial part of the water cycle and contributes to weather patterns.
