1. Evaporation: This is the process where liquid water absorbs heat energy and transforms into water vapor, which then rises into the atmosphere. This happens naturally on the surface of water bodies and even on moist surfaces like soil.
2. Boiling: This is a faster process where water is heated to its boiling point (100°C or 212°F) at standard atmospheric pressure. At this temperature, the water molecules gain enough energy to overcome their intermolecular forces and rapidly change into water vapor.
Both processes involve the addition of heat energy to break the bonds between water molecules and allow them to escape into the air as gas.
