What does steam come out of?

Steam comes out of water when it is heated to its boiling point, typically at 100 degrees Celsius (212 degrees Fahrenheit) at sea level. As water molecules gain energy, they transition from a liquid state to a gaseous state, forming steam. This process can occur from various sources, such as boiling water in a kettle, steam engines, or industrial processes. The visible vapor is essentially tiny water droplets that have condensed in the cooler air.
