The boiling point would rise as the pressure rises
The Dead Sea is below mean sea level for the earth; therefore, the pressure at the Dead Sea would be greater than at mean sea level and the boiling point of water would be above 100C.
The boiling point (of any compound) is ONLY affected by (vapor) pressure. Density of a gas (vapor) is another property that -in another way- may be affected by pressure.
The boiling point of water decrease when the altitude increase; the value at Johannesburg is near 94 0C.
Something boils when its vapor pressure equals the atmospheric (barometric) pressure above it. When the two are equal, that defines the boiling point.Therefore, you can either boil something by heating the liquid, and thus raising its vapor pressure (vapor pressure goes up with temperature), or you can boil something by reducing the atmospheric pressure above it until it matches the vapor pressure.See the Related Questions links to the left for more information about how the boiling point of water changes with elevation and atmospheric pressure.
As air pressure drops over the water surface the boiling point will drop and vice versa. So a kettle of water will boil at a lower temperature at the top of a mountain than at sea level because there's lower air or atmospheric pressure at the mountain top. Pressure is proportional to boiling point
The boiling point temperature of a compound increases as the pressure increases, until the pressure reaches the critical pressure of the compound. For water, you have : P ( kPa ) T ( C ) ------------ ---------- 1.0.............. 6.97 50....... .......81.32 100............ 99.61 101.325... 100.0 500........... 151.83 8000......... 295.01 20000....... 365.75 22064....... 373.95 ( Critical Point of H2O )
Increasing the pressure increases the boiling temperature
Pressure & Temperature :) Apex
There is a direct relationship between the temperature at which water boils and the air pressure on it. Higher pressure, higher boiling point. Lower pressure, lower boiling point.

Because the pressure could affect the temperature at which the water boils
Because the pressure could affect the temperature at which the water boils
The boiling point is that temperature when the SATURATEDvapor pressure of a liquidbecomes equal tothe surrounding pressure.Thus the higher the sorrounding pressure, the higher the boiling point.
Short answer: Pressure. Long answer: Pressure changes the boiling point of a substance. The higher the pressure, the higher the boiling point, and vice versa. For example, boiling water in the mountains is easier than boiling water at sea level. Note that boiling water is not necessarily hot. You can boil water at room temperature if the pressure is low enough (For example, using a vacuum generator)
The boiling point (of any compound) is ONLY affected by (vapor) pressure. Density of a gas (vapor) is another property that -in another way- may be affected by pressure.
The boiling point of water depends on the pressure. At 1 atmosphere pressure, the boiling point is 100ºC or 212ºF.
The boiling point of water is fixed but boiling points depends on the atmospheric pressure.
