At lower pressure or higher altitudes, the boiling point is lower. At sea level, pure water boils at 212 °F (100°C). At the lower atmospheric pressure on the top of Mount Everest, pure water boils at about 154 °F (68°C).
What will be the melting point of water at the top of a mountain?
The boiling temperature of water at top of the mountain will be less than 100 Celsius. Explanation: The air pressure is greater in sea level and less in mountain top because the air density and volume decreases with increase altitude.
What will be the boiling point of water at the top of a mountain where the atmospheric pressure is less than 1 atm?
Answer: if the atmospheric pressure is less than 1 atm then the boiling point of water will be less than 100° C.
Is the boiling point of water on a mountain top the same as that on the ground?
The boiling point of water on the mountaintop is not the same as that on the ground because the atmospheric pressure in the mountain regions is low. Therefore, the water starts boiling at a lesser temperature in the mountain regions.
Why does water boil at 71 on Everest?
At the top of the mount everest the atmospheric pressure is less than 1 atmosphere so water starts boiling at low temperature because boiling point is the temperature st which vapour pressure of the liquid becomes equal to the atmospheric pressure.
What is the boiling point of water at sea level in Celsius?
A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For example, water boils at 100 °C (212 °F) at sea level, but at 93.4 °C (200.1 °F) at 1,905 metres (6,250 ft) altitude.
What is the boiling point of water answer?
At sea level, water boils at 100° C (212° F).
