The manometer was placed in a thermostat maintained at a constant temperature (25掳C) throughout the whole series of experiments, whilst the capillary tube was kept in a cryostat at a different temperature, which could be readily altered. Viscosity of nitrogen up to 127 atm at 61.3 and 78.5...
[48], it shows that the transition from hadrons to quarks and gluons has behavior similar to helium, nitrogen, and water at and near their phase transitions in the ratio η/s. Near and below a critical temperature, Tc, the condensates of bosons or fermion pairs behave like superfluids, ...
Viscosity of Hydrogen—Nitrogen and Hydrogen—Ammonia Gas Mixtures The viscosity of the binary gas mixtures H2–N2and H2–NH3has been measured in the temperature range 33°—200°C and at pressure below 10 cm Hg, by using ... AK Pal,AK Barua - 《Journal of Chemical Physics》 被引量: ...
with atmospheric moisture happens easily and leads to the formation of insoluble ureas and carbon dioxide gas, which can result in pressure build-up in closed containers and viscosity increase of the product.Containers must therefore be absolutely dry and carefully sealed after congested wi...
The other electrospinning conditions were kept the same, with the single-nozzle electro- spinning being performed at ambient temperature (25 °C) with a relative humidity of 30%. Characterizations Viscosities of the polymer solutions were measured in terms of dynamic viscosity because the flow of ...
In this com- pound, aniline is selected as a PET donor because of its low pKa value and high electron transfer efficiency, allowing 1 to circumvent the interference from proton and metal ions under biological conditions; anthracene is linked to the aniline nitrogen, and plays two roles: ...

Assuming that the ideal gas law holds, find the amount of nitrogen gas in a container if P=0.836atm±0.003atm,V=0.01985m3±0.00008m3,T=298.3K±0.2K.Find the expected error in the amount of nitrogen. 3. The van der Waals equation of state is P+n2aV2V-nb=nRT.For carbon dioxide, a=...
All real fluids (except superfluids, such as liquid nitrogen) have some resistance to stress and fluid flow, but a fluid that has no resistance to shear stress is known as an ideal fluid or inviscid fluid. A real fluid with a nonzero viscosity is called a viscous fluid. The study of ...
