Steam turns into water at 212 degrees Fahrenheit (100 degrees Celsius) at standard atmospheric pressure. This is the condensation point, where the gaseous water vapor releases its latent heat and transitions back into its liquid state. The temperature remains constant during this phase change.
Water turns to steam at 100 degrees Celsius (212 degrees Fahrenheit) at standard atmospheric pressure. This is its boiling point. At this temperature, the water molecules gain enough energy to overcome the intermolecular forces and transition from a liquid to a gaseous state. This phase change is fundamental to many natural and engineered systems, including weather patterns and power generation.
