The boiling point of water is 212 degrees Fahrenheit at sea level. This temperature is achieved when the air pressure is standard (1 atmosphere). When water reaches this boiling point, it transforms from a liquid to a gas (steam) as heat energy causes the water molecules to move rapidly and escape into the air. However, it's worth noting that the boiling point can change with variations in altitude and atmospheric pressure. For instance, at higher altitudes, water boils at lower temperatures due to decreased pressure, which is important for cooking in mountainous regions.
