Who invented the pycnometer?
1000-1048: Pycnometer: Abū Rayhān al-Bīrūnī
When was the pycnometer invented?
According to the Wikipedia article on the gas pycnometer, the first patent was filed by John E. Shea on 13 Nov 1978 and it was issued on 08 Apr 1980.
What is the instrument that specific gravity of liquid is measured?
Pycnometer, Digital density meter
What is the meanig of pycnometer?
A gas pycnometer operates by detecting the pressure change resulting from displacement of gas by a solid object. Expanding a quantity of gas at known pressure into an empty chamber and measuring the pressure establishes a baseline.Then a sample is placed in the chamber and the chamber is resealed. The same quantity of gas at the same pressure is again expanded into the sample chamber, and the pressure is measured. The difference in the two pressure combined with the known volume of the empty sample chamber allows the volume of the sample to be determined by way of the gas law. --GOLD APP INSTRUMENTS
What is the instruments for density?
There are many types density, like true density, tap density, bulk density etc. Can use analyzer like G-DenPyc 2900 gas pycnometer analyzer to measure them. Aerometer or Hydrometer for density of liquids, Dasymeter for density of gases and Resonant Frequency and Damping Analyser (RFDA) for density of solids.

What are the advantage and disadvantages of pycnometer?
__1__
Why the pycnometer method more accurate than the hydrometer method?
The pycnometer method is more accurate than the hydrometer method because it uses an analytical balance.
When was the pycnometer invented?
According to the Wikipedia article on the gas pycnometer, the first patent was filed by John E. Shea on 13 Nov 1978 and it was issued on 08 Apr 1980.
Method to obtain density of liquid?
Using a densimeter or a pycnometer.
What has the author A M Geddis written?
A. M. Geddis has written: 'Rapid estimate of solid volume in large tuff cores using a gas pycnometer' -- subject(s): Sampling, Soils, Volcanic ash, tuff, Pycnometer
What is the instrument that specific gravity of liquid is measured?
Pycnometer, Digital density meter
Why is a conical cap provided to a pycnometer?
A conical cap is provided to a pscnometer to determine the volume of the test sample.
How is a substance's density calculated?
Density is the ratio beween the mass and the volume.Many devices exist in laboratory do determine the density: special analytical balance, pycnometer, helium pycnometer, densimeter (for liquids), electronic densimeter (for liquids) etc.; for perfect geometrical shapes the measurement of dimensions-calculation of volume-weighing are sufficient.
What does a pycnometer measure?
A major application of a micropycnometer is that it allows one to measure the density of a solution when one only has a small volume available. For example, I would like to know the density of an H2018 sample. This stuff costs several hundred dollars per mL. My desitometer requires a minimum of 1.2mL. If I had a micropycnomter, I could get away with only needing a fraction of that amount
What are the advantage and disadvantage of pyconometer?
An advantage of using a pycnometer is that the instrument does not have to be in direct contact with the fluid it is measuring.Ê A disadvantage could be that it can be easily broken as it is made out of glass.
What measurement tool is used to measure mass?
A pycnometer is such a tool. It is a carefully calibrated glass container with a close-fitting stopper. Since the volume is accurately known, a simple mass balance may be used to determine the mass of your unknown liquid. There are also techniques available for measuring the density of a non-soluble powder, using the same apparatus. In normal use, the pycnometer is filled with your unknown fluid, and weighed. Then the device is cleaned thoroughly of any residue, and a reference fluid such as water or Mercury is used to fill the pycnometer. Simple arithmetic suffices to work out the density of the unknown material. Sometimes called the 'specific gravity bottle'.
