Question
Sea water boils below $100^\circ\ C$. [True/ False]
✓
Answer
False.
Pure water boils at $100$ degrees Celsius under normal atmospheric pressure, but the Dead Sea surface is so low (more than $400$ meters below "sea level") that water boils at about $101$ degrees there. It does boil at a higher temperature because of the high amounts of non-volatile solids.
