I may quote, e.g., the exhaustive work of Rühlmann, where, in the chapter on the history of the molecular theory, Joule is only alluded to, and immediately afterwards the theory of Krönig is given in extenso, without any hint that it is practically identical with that given by Joule...
At a proportion of 10% hydrophilic particles the gas mixture is solid-like adjacent to the wall. The distribution of velocity shows that the flow speeds up with an increase in hydrophobic particles and the slip velocity of gas mixtures changes gradually from negative to positive....
During more than a decade, kinetic phenomena arising in gases under velocity-selective excitation have been the object of many studies (see, in particular, Refs. [1–6]). When the momentum relaxation rates v e for the excited and v g for the ground-state molecules are different, the ...

If 'v' is the velocity of sound in a gas , then 'v' is directly proportional to (here M , d and T represents molecular weight of gas , density of gas and its temperature , respectively.) A√M B1√d C√T Dboth (b) and (c)Submit Molecular mass of a gas is 78 . Its densi...
The movement of one gas through another by thermal random motion. Diffusion is a very slow process in air because the mean free path is very short (for N2 at STP it is 6.6x10-8 m). Given the nitrogen molecule’s high velocity, the collision frequency is very high also (7.7x109 coll...
Based on the postulates of kinetic molecular theory of gases and root mean square velocity \(‘{\rm{C}}’\) the Kinetic gas equations, \({\rm{PV = }}\frac{{\rm{1}}}{{\rm{3}}}{\rm{mn}}{{\rm{C}}^2}\) is derived, where \({\rm{P}}\) is pressure, \({\rm{V}}\)...
The lower bound estimate for the maximum equilibrium characteristic velocity established for a monatomic gas is proved to be valid also for a rarefied polyatomic gas, that is, the estimate is independent of the degrees of freedom of a molecule. As a consequence, also for polyatomic gases, when...
Expressing mass in kilograms and speed in meters per second will yield energy values in units of joules (J = kg m2 s–2). To deal with a large number of gas molecules, we use averages for both speed and kinetic energy. In the KMT, the root mean square velocity of a particle, urms...
