The boiling point of water on a mountain top is less than on the ground. At sea level, atmospheric pressure is 14.7 psia and water boils at 212℉ (100℃). At an elevation of 8,000 feet (2,438 meters), water boils at 197℉ (91℃) and pressure is 10.9 psia.
Is the boiling point of water on the mountaintop 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.
What is the boiling point of water on top of a mountain?
The boiling point of water varies with atmospheric pressure. 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).
Does water boil easier in the mountains?
At a higher elevation, the lower atmospheric pressure means heated water reaches its boiling point more quickly—i.e., at a lower temperature. … This is the opposite of what many people suppose: that water takes longer to boil on high. As we’ve just demonstrated, boiling water at altitude is quicker.
Will water have the same boiling point on the hills as it is on plains justify your answer?
in the hills the atmospheric pressure is lower than that in the plains and therefore water boils at a temperature lower than 100oC causing an increase in cooking time.
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 is the boiling point of water?
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. For a given pressure, different liquids will boil at different temperatures.
What is the boiling point of water in hilly regions?
Boiling point of pure water at elevated altitudes
|Altitude, ft (m)||Boiling point of water, °F (°C)|
|0 (0 m)||212°F (100°C)|
|500 (150 m)||211.1°F (99.5°C)|
|1,000 (305 m)||210.2°F (99°C)|
|2,000 (610 m)||208.4°F (98°C)|
What boils faster ice or water?
Because it takes cold water some time to reach the temperature of hot water, cold water clearly takes longer to boil than hot water does. … “It all depends on how fast the cooling occurs, and it turns out that hot water will not freeze before cold water but will freeze before lukewarm water.
