Although molecules (tachyons) of the tachyon gas moves with superluninal velocities, the mean motion of these molecules appears to be less, than the ... YA Rylov - 《International Journal of Theoretical Physics》 被引量: 18发表: 2013年 加载更多来源...
Preferably, the transfer of charge from surface 12 to the gas molecules 18, and from the gas molecules 18 to surface 14, is facilitated by transferring electrons. The charge transfer may be bidirectional, with molecules 18 being negatively charged while moving from surface 12 to surface 14, ...
3 (a) (i) One of the assumptions of the kinetic theory of gases is that the motion of gas molecules is random. Therefore explain why the average momentum of the gas molecules in a container is zero.[2](ii) According to the kinetic theory of gases, explain how a gas exerts a pressur...
Random motion, also known as Brownian motion, is the chaotic, haphazard movement of atoms and molecules.Random motion is a quality of liquid and especially gas molecules as described by the kinetic theory. The botanist Robert Brown first noticed this phenomenon in 1827, and Albert Einstein later ...
The self‐diffusion coefficient resulting from the time‐correlation function agrees with that of the Chapman–Enskog solution. In addition, the time‐correlation function of molecules in gas mixtures is examined. The corresponding diffusion coefficient decreases with increasing the concentration of the ...
Kr枚nig has recently proposed that the molecules of a gas do not oscillate about definite positions of equilibrium, but that they move with constant velocity in straight lines until they strike against other molecules, or against the surface of the container. I share this view, but believe ...
This paper applies the Boltzmann method of gaseous kinetics to the problem of positive ions moving through a gas under the influence of a static, uniform electric field. The ion density is assumed to be vanishingly low, but the field is taken to be strong; that is, the energy which it im...
The Brownian motion of a hard spherical particle in a gas whose molecules interact only with the particle but not with each other is considered from three points of view. (a) The generalized Fokker‐Planck equation for the process is derived by the classical method of Lord Rayleigh. (b) The...
1.The lower the temperature, the slower the motion of the molecules.温度越低,分子运动越慢。 2.The molecules of gases move more freely than do those of liquids and solids.气体分子运动比液体分子和固体分子运动更为自由。 3.Micronozzle flow based on simulation of molecule movement基于分子运动模拟...
A kinetic–theoretic approach is employed under the condition that the distance between the two plates is comparable to the mean free path of the gas molecules and/or the frequency of oscillation of the plate is comparable to their mean collision frequency. More specifically, the Bhatnagar–Gross...
