Which of the following has maximum root mean square velocity?
Thus , H2 gas with the lowest molar mass the maximum rms velocity.
Which gas has maximum rms velocity?
H2
What is the ratio of most probable speed and average speed of ideal gas molecules?
Complete answer: For the ratio of root mean square speed, average speed and most probable speed, we use the formulae Vrms=√3RTM,Vav=√8RTπMand Vmps=√2RTM.
What is RMS speed Class 11?
Root Mean Square speed of gas is the square root of the mean of the square of the speed of individual molecules. Molar volume is the volume occupied by molecules of any (ideal) gas at N.T.P.
What temperature is most probable speed?
Figure 1 shows the Maxwell-Boltzmann distribution of speeds for a certain gas at a certain temperature, such as nitrogen at 298 K. The speed at the top of the curve is called the most probable speed because the largest number of molecules have that speed.
Under what conditions will a real gas behave ideally?
Generally, a gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to intermolecular forces becomes less significant compared with the particles’ kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.
Which of the following is not a correct postulate of the kinetic theory of gases?
The molecules are perfectly elastic. It is not the postulate of kinetic theory. The correct postulate or assumption is “The molecule collisions are perfectly elastic.
Which is not correct for gases?
Gases do not have a definite shape and volume. Volume of the gas is equal to volume of container confining the gas. Mass of gas cannot be determined by weighing a container in which it is enclosed.
What is the average translational kinetic energy of molecules in an ideal gas at 37 OC?
The average translational energy of a molecule is given by the equipartition theorem as, E=3kT2 where k is the Boltzmann constant and T is the absolute temperature. For T=(37+273)K we are easily in the required high-temperature limit.
