4 (a)Describe the motion of molecules in a gas, according to the kinetic theory of gases.[2](b)Describe what is observed when viewing Brownian motion that provides evidence for your answer in (a).[2](c)At a pressure of 1.05 ×105P a and a temperature of 27C, 1.00mol of helium ...
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...
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, ...
The agitation and migration of small colloidal particles has been known since the work of Robert Brown in the early nineteenth century. This thermal motion is likened to the diffusion of gas molecules in a nonuniform gas. The applicability of Fick's equations for the diffusion of particles in ...
Particles less than 0.5 µm are small enough to be perturbed by surrounding gas molecules. This bombardment (impaction with gas particles) can interrupt intended particle routes, which will move particles towards the surface of the respiratory tract, with the observed diffusivity being inversely...
In addition, there is only one study in which the Brownian motion has been used so far in the area of optimization: An optimization method was developed by using the Brownian motion of gas molecules in nature and very successful results were obtained in the study [29]. These results were ...

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 ...
What Is Random Motion? 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, ...
