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?
You need a thermometer.
Why is the thermometer not suitable to measure the freezing point and boiling point of water?
Although a thermometer CAN be used its presence affects the temperature.
What effect does the use of an uncalibrated thermometer have on the boiling point of a liquid?
The thermometer's reading of the point the liquid boils may not be accurate.
Why are the temperatures of the melting point of ice boiling point of water called fixed point in calibrating the thermometer?
it is because they were consistent at melting and boiling point
The result of the weight of the column of air pushing down on an area?
Air pressure, barometric pressure, the boiling point of water.

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.
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.
Which thermometer is most suitable for measuring boiling point of water mercury or alcholic thermometer?
Which thermometer is most suitable for measuring boiling point of water mercury or alcoholic thermometer
What is the boiling point of water in Glencoe Minnesota?
212? Not exactly. Altitude comes into play in finding exact boiling points. 212 degrees Fahrenheit is boiling point at sea level. At higher altitudes (as on a mountain) atmospheric pressure falls, and so does boiling point. Barometric pressure can also play a part. There are conversion charts around the web to help find exact measurements. Altitude of St. Paul Minnesota is 702 ft. , thus bringing boiling point down to approx 210.7 degrees. Nearby Glencoe MN is probably about the same. Now you're ready to calibrate your candy thermometer! PT Berger
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.
What is the most suitable thermometer for measuring boiling point of water?
- a thermometer with mercury - a thermometer with thermoresistance

Alcohol thermometers cannnot be used for measuring high temperaturewhy?
Alcohol's boiling point is fairly low. At higher pressures, a lot of pressure would build up; this could break the thermometer.Alcohol's boiling point is fairly low.
