in Lower pressure water does not have to get as hot to boil
This is possible only when a colder air front move to this zone with a lower pressure.
Studies have shown that physical contact with a pet can lower high blood pressure, and improve survival rates for heart attack victims. There is also evidence that petting an animal can cause endorphins to be released.

The lower trunk of a pig is called the posterior region. The trunk is divided into an upper, middle, and lower region due to its size and functions.
The bones present in our lower legs are tibia and fibula.
The atmospheric pressure is lower. When you are boiling the water, the water's vapour saturation pressure is able to match the atmospheric pressure faster therefore it boils faster and at a lower temperature.
Water boils when its internal pressure reaches that of the atmospheric pressure. Therefor, if one lowers the atmospheric pressure, the water would boil at a lower temperature (in fact, one can make water boil at room temperature by dramatically lowering the atmospheric pressure).
The boiling point of any liquid is the temperature at which its vapor pressure becomes equal to the atmospheric pressure. So if the atmospheric pressure is lower, it will take a lower temperature to make the vapor pressure equal to that of atmospheric pressure. At hill-stations, the air is generally thinner due to the altitude and the atmospheric pressure is also lower. Here, it requires less than 100oC temperature to reach the point where the vapor pressure of water reaches that of air. So, water boils below 100oC at hill stations.
Water boils at lower temperatures at higher altitudes because the atmospheric pressure is lower. In a valley, the air pressure is greater, which allows water to reach a higher temperature before boiling. At higher altitudes, where the air pressure is lower, the boiling point of water decreases.
At a high altitude, the atmospheric pressure is low, so water boils at a lower temperature; as it boils, it loses heat.
You are probably above sea level so that the atmospheric pressure is lower than sea level pressure. Water boils at lower temperatures as the pressure is lowered. The other possibility is that the thermometer is not calibrated correctly, but I'd go with the atmospheric pressure is below sea level pressure.
The lower the pressure then the lower the temperature that is required to make it boil. Water at the top of Mount Everest boils well below 100 degrees centigrade due to the lower atmospheric pressure.
The boiling of any liquid is tied in to the atmospheric pressure, in an open system. Every liquid has it's own vapor pressure, that is the balance between the vapor and liquid phase. When atmospheric pressure decreases, the vapor pressure increases since now there is greater space for the molecules of the liquid to come into vapor phase. At higher altitudes, the atmospheric pressure is lesser, that is, the air is thinner. Thus the liquid can attain higher vapor pressure faster and boil at a lower temperature.
Ya ........ if you have an egg on the top of high mountain the altitude and less air density causes lower boiling points and when you get higher it reduces the boiling point of the water and it is due to atmospheric pressure.Boiling is directly proportional to atmospheric pressure which becomes lower when we go above the sea level example mountainous areas.

Water only boils at 100 degrees ( in C ) when the pressure on it is standard atmospheric pressure. In Denver, it boils at a lower temperature, and in a pressure cooker, it can get a lot hotter than that and still not boil. At the bottom of a geyser, the pressure is more than atmospheric pressure because of all the water laying on top of the lowest layer, so it can go higher than 100 without boiling.
Water boils at 100 degrees Celsius or 212 degrees Fahrenheit under standard conditions at sea level (at one atmosphere of pressure).The boiling point of water and any other substance depends on the atmospheric pressure, which changes with elevation. At higher altitudes, the pressure is lower, and so water boils at a lower temperature. If the barometric pressure is not at the standard value, the boiling point will be different. For example, water boils at 72 degrees Celsius on Mount Everest.See the Related Questions links to see how atmospheric pressure and elevation affect the boiling point of water.At 1 atmosphere water boils at:100 oC;373 K; or212 Fahrenheit
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.
