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.
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.
Boiling point of water at absolute 0 pressure?
0 degrees Kelvin. (Or -273.16 degrees Celsius.)
What instrument measures boiling point?
You need a thermometer.
What is boiling point on kelvin and on celsius scale?
On Celsius scale it is 100 C and on Kelvin scale it is 373.15 K. The Kelvin scale starts at absolute zero and is used in scientific laboratories. Celsius is for general use and set 0 and 100 as melting and boiling point of water respectively.Different substances have different boiling points. For the same substance, the boiling point also depends on the pressure, although atmospheric pressure is often assumed.

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
Boiling point of water at absolute 0 pressure?
0 degrees Kelvin. (Or -273.16 degrees Celsius.)
What is the most suitable thermometer for measuring boiling point of water?
- a thermometer with mercury - a thermometer with thermoresistance
Why would it be necessary to attech a manometer to the hypsometer?
A manometer is a device that measures fluid pressure. A hypsometer is an instrument that measures height or elevation. One way to measure elevation is by using atmospheric pressure, which decreases with altitude. A hypsometer that uses this principle is called a boiling point apparatus or a pressure hypsometer. It consists of a thermometer and a vessel in which water is boiled. The boiling point of water depends on the atmospheric pressure, so by measuring the temperature of the boiling water, the pressure can be inferred and then converted to elevation. A manometer can be attached to the hypsometer to measure the pressure of the steam inside the vessel directly, without relying on the thermometer. This can improve the accuracy and reliability of the elevation measurement, especially if the thermometer is not calibrated or affected by other factors. A manometer with only one side open to the atmosphere is an ideal device for measuring gauge pressures, which are relative to the atmospheric pressure. The gauge pressure is p g = hρg and is found by measuring h, the height difference of the fluid columns in the U-shaped tube of the manometer. By knowing the gauge pressure and the atmospheric pressure, the absolute pressure inside the vessel can be calculated and then used to determine the elevation.
In order to bring ethanol to a boiling point while keeping the temperature at 35 degrees what would the pressure need to be reduced to?
The exact pressure would vary dependant on if you are referring to the boiling point of an ethanol azeotrope or absolute ethanol. For example the boiling point at 1 ATM for azeotropic ethanol is 78.15C and for absolute ethanol it is 78.4C. At a temperature of 35.0C azeotropic ethanol will boil in a vacuume pressure of 159.8 mbar/hPa or 119.9 mmHg/Torr where as absolute ethanol boils at a slightly lower pressure of 158.6 mbar/hPa or 119 mmHg/Torr.
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.

What is the definition of celsius?
It is a relating to a temperature scale that registers the freezing point of water as 0° Celsius and the boiling point as 100° Celsius under normal atmospheric pressure.

Why will water boil at 96 Celsius?
it may be because of decrease in pressure.it can also be due to many other factors we define the boiling point as the temperature in which the molecules of the liquid leaves the surface and its pressure equals the atmospheric pressure so if we reduce pressure we can reduce boiling point
How are temperature and humidity not related?
By marriage. Humidity and temperature are related. The maximum absolute humidity increases with temperature and pressure (up to the boiling point).
