Nitrogen density

Vp is the pore volume estimated from N2 isotherms at P/Po=0.6 (P/Po=0.9 for sample 4) using the bulk liquid nitrogen density... 

If more than 100 photoelectrons are produced in each event, the uncertainty (one standard deviation) in the actual number of photoelectrons, N, may be approximated by /N and the fractional uncertainty is [Pg.264]

The relative fluctuations in nitrogen density versus crank angle are indicated by the solid curve shown in Figure 5. Prior to ignition, the fluctuation level was quite low. The fluctua-... 

The strongest evidence lies in the systematic reduction of electron concentration found in reactively sputtered films as nitrogen density is increased in the growth plasma [1]. 

Backward extrapolation of the linear multilayer section of the as-plot allows us to assess the total micropore capacity (as indicated in Chapter 8) and hence to evaluate the effective micropore volume, v(mic, S). The values of vp(mic, S) in Table 9.1 were obtained by making the usual assumption that the pores are filled with liquid nitrogen (density 0.808 g cm-3).

A plot of PI[V Pq -/ )] versus P/Pq should give a straight line from which the slope and intercept can be solved to yield V. From V, the specific surface area can be calculated if it is known how much area each molecule occupies on the surface a. For nitrogen gas = 16.2 x 10 ° m, based on the liquid nitrogen density of 0.81 gml and assuming a close-packed sphere arrangement. In this case the total surface area per gram, Aj,p = where is the... 

Eq.(6.1 l-14a) is calculated from the liquid nitrogen density, which is taken as 0.808 g/cm (Hovarth and Kawazoe, 1983). 

The slope of assimilation rate relationship with conductance diminishes markedly in high conductances, because the relationship between carboxylation and p-[ is a biphasic non rectangular hyperbola. This slope effect tends to be great if very high conductances (g) and high photosynthetic fluxes (A) are involved leaf water conductance and nitrogen density are potentially involved in creating more or less pronounced effects on p determinations.

Ramsay was informed about Lord Rayleigh s problems with nitrogen density and cooperation was established. Different experiments were carried out in order to isolate the stranger in the atmosphere. 

Fig. 3.17. The dissociative charge transfer He+ + N2 —> N+ + He + N has been used to follow the time dependence of the nitrogen density in the trap at a temperature of 38K. The gas flow has been hold constant gas at 3 X 10 mbar Is. At the beginning of the experiment, the pumping speed of the cold clean surfaces maintains a rather low stationary density. With increasing time, saturation reduces the sticking efficiency.

Twenty-five milliliters of liquid nitrogen (density = 0.807 g/mL) is poured into a cylindrical container with a radius of 10.0 cm and a length of 20.0 cm. The container initially contains only air at a pressure of 760.0 mmHg (atmospheric pressure) and a temperature of 298 K. If the liquid nitrogen completely vaporizes, what is the total force (in lb) on the interior of the container at 298 K ... 

Experimental results are done by N2 adsorption at 77.4 K. The value was calculated by Brunauer and Emmett [5], which corresponds to liquid nitrogen density. Thus,... 

LNGs are colourless, multi-component liquid mixtures of methane (density 422 kg/m ), ethane (density 544 kg/m ) and smaller proportions of propane (density 581 kg/m ), higher hydrocarbons, carbon dioxide and nitrogen (density 807 kg/m ), with normal boiling point at 1 bar in the range 112-120 K (or -161 to -153 °C).
