How does the boiling temperature of water change with altitude?

Depending on the altitude the boiling point will differ. This calculator will give you the boiling point of the altitude that you desire to discover: http://www.csgnetwork.com/h2oboilcalc.html


Why would water boil at less than 100 degrees on top of a mountain?

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.


What is the boiling point of water at sea level xy?

Answer:The boiling point of water at sea level is 100oC (212oF). Water boils when the pressure of the vapor is equal to the surrounding pressure. Since atmospheric pressure is reduced at higher altitudes it takes less energy (and therefore less heat) to boil water. So to put it simply the higher your altitude the lower the boiling point.


What is the boiling point of water in degrees Celsius?

The boiling point of water is 100 degrees C, but only at sea level, or in other words, at an atmospheric pressure of 1013.2 millibars. As the altitude increases (or the pressure decreases, same thing), the boiling point goes down. This happens at the rate of about 1 degree C for every thousand feet of altitude gained or for every 35 millibars of pressure lost. The boiling point of pure water is 100 0C at 760 mm col. Hg. ((101.325 kPa of atmospheric pressure). This is not a coincidence. The Celsius scale was originally defined around the boiling and freezing points of water.


What is the physical state of argon at -197 and normal atmospheric pressure?

Argon will be a gas at -197°C and normal atmospheric pressure, as it has a boiling point of -185.8°C at atmospheric pressure.

Why is the boiling point in Durban different from that in Johannesburg?

Boiling point is dependent on air pressure. Air pressure is dependent on altitude. Durban is coastal, almost sea level. Johannesburg is inland, quite a bit higher. High altitude = low air pressure = low boiling point.


Why the boiling point of water is 98 in Kaghan?

The boiling point of water decrease when the altitude increase and the atmospheric pressure decrease.


How does altitude effect boiling points?

The higher the pressure, the higher the boiling point. Boiling occurs when the atmospheric pressure equals the vapor pressure. So, at higher altitudes where the atmospheric pressure is lower, the vapor pressure is also lower which in turn creates a lower boiling point which causes foods to have to cook longer.


Why altitude affects boiling point?

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.

What is the property of matter that is dependent to altitude?

The property of matter that is dependent on altitude is atmospheric pressure. Atmospheric pressure decreases with increasing altitude due to the decrease in the weight of the air above. This decrease in pressure affects various aspects of the environment, such as boiling points of liquids and gas behavior.


Why boiling point of water is not fixed?

The boiling point of water can vary based on factors like altitude and atmospheric pressure. At higher altitudes, where the atmospheric pressure is lower, water boils at a lower temperature. This is because the lower pressure makes it easier for water molecules to escape into the air as vapor.


Why boiling point of water in Shimla in lower than that in Delhi?

It depends what your altitude is compared to sea level. The lower below sea level you are, the more atmospheric pressure there is thus increasing boiling point; pressure raises the boiling point. That is why your auto has a pressurized cooling system - to stop boil over.


Is it true that the boiling point of a liquid remains constant at all altitudes?

No. Atmospheric pressure falls the higher you go. The boiling point of a liquid varies with ambient pressure. If the pressure is lower then the boiling point will be lower.


Is it true that boiling point remain constant in all altitudes?

No, the boiling point decrease at high altitudes.


What would be the boiling point of alcohol at a higher altitude?

The boiling point of alcohol decreases at higher altitudes due to the lower atmospheric pressure. As altitude increases, atmospheric pressure decreases, causing liquids to boil at lower temperatures. This means that alcohol will boil at a lower temperature at higher altitudes compared to sea level.


What effcet does altitude have on boiling point of water?

Higher altitude decreases the boiling point of water. Boiling point is defined as the point at which the vapour pressure of the substance above the liquid is equal to the external atmospheric pressure. Since the external atmospheric pressure is lower at higher altitudes, a lower vapour pressure of water is required for water to boil and therefore a lower temperature is required to achieve the desired vapour pressure.


Does melting point change from altitude to altitude?

Yes, the melting point of a substance can change with altitude due to the variation in atmospheric pressure. As altitude increases, atmospheric pressure decreases, which can affect the boiling and melting points of substances. Generally, lower pressure at higher altitudes can result in lower melting points for many substances.
