Because in the mountaintop the pressure is lower than in the sea level; I think.
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.
It boils at a lower temperature because of the less energy needed.
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.
Water typically boils at 100 degrees Celsius (212 degrees Fahrenheit) at sea level. However, this boiling point can vary with changes in atmospheric pressure; for example, at higher altitudes where the pressure is lower, water boils at a lower temperature.
it doesnt it just boils it faster.
Water boils at a lower temperature in high altitude areas because the atmospheric pressure is lower at higher elevations. The lower air pressure reduces the boiling point of water. This means that the water reaches its boiling point quicker, even though the temperature is lower than at sea level.
Salt water freezes at a lower temperature and boils at a higher temperature.
Besides temperature, atmospheric pressure significantly affects the boiling point of water. At higher altitudes, where atmospheric pressure is lower, water boils at a lower temperature. Conversely, at increased pressure, such as in a pressure cooker, water boils at a higher temperature. This relationship is crucial for cooking and various scientific applications.
Water boils at lower temperatures at higher altitudes because the atmospheric pressure is lower at higher altitudes. This lower pressure decreases the boiling point of water. At sea level, the atmospheric pressure is greater, causing water to boil at 100 degrees Celsius.
Water boils at 100oC at the air pressure found at sea level. The temperature at which water boils becomes lower where there is lower air pressure, so water would boil at a lower temperature near the top of a high mountain. It boils at a higher temperature when the air pressure is higher, in a location below sea level like near the Dead Sea, for example.
without salt water melts at 0 c or 32 f. It boils at 100 c or 212 f. Depending on the amount of salt, it melts at a lower temperature and boils at a higher temperature.
Water boils at 373.15 Kelvin.
