Specific Gravity of gasesis normally calculated with reference to air - and defined asthe ratio of the density of the gas to the density of the air- at a specified temperature and pressure. The Specific Gravity can be calculated as SG = ρgas/ ρair(3) where SG = specific gravity of g...
1.An amount equal to the density of a solid or liquid divided by the density of an equal volume of water that is at a temperature of 4°C (39°F). 2.An amount equal to the density of a gas divided by the density of an equal volume of air or hydrogen that is at a specified ...

Density,specific Density,specific weight与specific gravity之⽐较Density Density is defined as an objects mass per unit volume. Mass is a property.Mass and Weight - the Difference! - What is weight and what is mass? An explanation of the difference between weight and mass.The density can be ...
[Class 97 (iii)] In apparatus in which the density of a gas is measured by the buoyancy of a light body in an atmosphere of the gas whose density is to be determined the light body comprises a flexible hermetically sealed body 1 filled to such an extent with a gas that it is ...

Recent measurements of the constant-volume specific heat of argon (and of oxygen) at critical density and close to the critical point are compared with calculations based on the three-dimensional nearest-neighbor lattice gas models. It is argued that the configurational specific-heat density C(T)...
There is described a method and device for measurement of the specific density of a gaseous or liquid medium, whereby a pulsed acoustic signal is injected into the measured medium by means of a transmitting transducer, the signal is dete... P Hauptmann,Puttmer, Alf,Schafer, Robert 被引量: ...
You can also use it to calculate the density of gases, as in our ideal gas density calculator. What is the specific gas constant? The specific gas constant is defined as the ratio of the molar gas constant to the molar mass of the gas and is measured in the units, J/kg⋅KJ/kg...
Density of a liquid is estimated by using an instrument called a hydrometer. It almost looks like a thermometer with a weighted bulb at the bottom. This weighted bulb helps the hydrometer to float in the liquid. Some marked lines are present on the hydrometer that indicate the Density of a...
