FACT CHECK #PYD4M2WX

WHAT WE FOUND

The claim is accurate. The USDA Food Safety and Inspection Service states that at sea level, water boils at 212 °F (100 °C), and that the boiling point falls as atmospheric pressure decreases with elevation 1. Britannica gives the same figure: at sea level, water boils at 100 °C (212 °F), and at higher altitudes it boils at a lower temperature 6. Pew Research notes that the boiling point depends on location, which is consistent with the sea-level standard 7. Educational sources also tie the 100 °C figure to standard pressure of 1 atm at sea level 89. One minor caveat is that actual atmospheric pressure at sea level varies slightly with weather, so the exact boiling point shifts a little. The 100 °C figure is the standard value at 1 atm, and the claim states it correctly.
