Recording the barometric pressure is important because it affects the boiling point of water. Variations in barometric pressure can lead to changes in the boiling point, which in turn can impact the accuracy of the calibration process for the thermometer. This information allows for adjustments to be made to ensure the calibration is done correctly.

What types of equipment would be used to measure the boiling point of a liquid?

You need two tools. To measure the air pressure you use a barometer and to measure the temperature at which the substance boils you use a thermometer. The boiling point is defined as the temperature at which the vapor pressure equals atmospheric pressure.


Why is the boiling point of water lower in Shimla than in Delhi?

I think that Shimla is at higher elevation than Delhi is. If that is the case, than it is because the barometric pressure goes down at higher elevations.See the Related Questions link to the left of this answer for more about how the boiling point of water is affected by the air pressure.


What instrument measures boiling point?

A thermometer is typically used to measure the boiling point of a substance. It can accurately measure the temperature at which a liquid changes state from a liquid to a gas during the boiling process.


Why is boiling dependent on pressure?

Boiling is dependent on pressure because the pressure affects the boiling point of a substance. When the pressure is higher, the boiling point of a substance is also higher, and when the pressure is lower, the boiling point is lower. This is because pressure affects the vapor pressure of the substance, which needs to equal the atmospheric pressure for boiling to occur.


If a thermometer sitting in boiling water registers less than 100 degrees what is wrong?

lower air pressure, ice water will boil if put in a sealed vessel and a vaccum is applied. A boiling point of 100`c assumes one atmosphere of pressure, this like the difference in cooking at sea levl versus cooking on a mountain top.

What is the upper fixed point in the thermometer?

The upper fixed point on a thermometer is the temperature set at 100 degrees Celsius, which corresponds to the boiling point of water at standard atmospheric pressure. This fixed point is used as a reference point for calibrating the thermometer.


The result of the weight of the column of air pushing down on an area?

Air pressure, barometric pressure, the boiling point of water.


You are trying to calibrate a celsius thermometer. when you place the thermometer into a beaker of boiling water what should the thermometer read?

The thermometer should read 100 degrees Celsius when placed in boiling water at standard atmospheric pressure.


What effect would a decrease or increase in barometric pressure have on the boiling point?

If you were to travel to Denver, the mile high city, air pressure is reduced. This makes it easier for gas molecules to escape the liquid, hence the boiling point lowers. On the other hand, when pressure increases, gases have a harder time escaping the liquid so the boiling point must increase.

What does barometric pressure have to do with evaporation?

Above the surface of liquid water is a layer of water vapor. It has pressure. The atmosphere also has pressure. It pushes against the water vapor. The water vapor pushes against the atmosphere. It is called vapor pressure. It is related to temperature. When the vapor pressure equals barometric pressure, water boils. Normally this occurs at 100C or 212F. If you reduce the barometric pressure, you can reduce the boiling point of water. So when the barometric pressure is lower, the water vapor above the water has an easier time mixing with the atmosphere. As it mixes with the atmosphere, it is replaced by vapor from the water. It evaporates.


What is the actual temperature of boiling water?

The temperature of boiling water is about 100 °C (212 °F) . But keep in mind that the temperature varies depending on the altitude at which the water is boiled and also the local barometric pressure. For example, in a city that is one mile above sea level where the barometric pressure is, say, 29.92, the water will boil at a temperature of just 202.6 F.

Does water boil at high temperature at high altitude?

It depends on barometric pressure rather than height ... but approximately at 2000 feet the boiling point drops to 208 degrees at 7000 feet the boiling point is about 199 degrees.


Why did your thermometer never hit 100 degrees Celsius when boiled?

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.


How does the boiling point of a liquid vary with pressure?

Something boils when its vapor pressure equals the atmospheric (barometric) pressure above it. When the two are equal, that defines the boiling point.Therefore, you can either boil something by heating the liquid, and thus raising its vapor pressure (vapor pressure goes up with temperature), or you can boil something by reducing the atmospheric pressure above it until it matches the vapor pressure.See the Related Questions links to the left for more information about how the boiling point of water changes with elevation and atmospheric pressure.


Boiling water temperature in digital thermometer?

Boiling water temperature is typically recorded at 100 degrees Celsius or 212 degrees Fahrenheit on a digital thermometer at standard atmospheric pressure. It's important to ensure accurate calibration and proper immersion of the thermometer in the water for an accurate reading.
