212°F (100°C) is the boiling point of water at standard pressure — the second fixed reference point of the Fahrenheit scale. At high altitudes water boils lower: 202°F in Denver, ~160°F atop Everest. In cooking, a rolling boil at 212°F is used for blanching vegetables, cooking pasta, making stock, and sterilizing canning equipment. Steaming is actually gentler than many realize because the steam itself is only 212°F.
Gozonji desu ka?
Adding salt to water raises the boiling point, but minimally. You would need ~230 g of salt per liter to raise it by just 2°F (1°C).

Yes. 212°F equals exactly 100°C at standard atmospheric pressure.
Lower atmospheric pressure means less energy is needed for vapor pressure to equal atmospheric pressure.
