The temperature at which the rms speed of hydrogen molecules is equal to that of oxygen molecules at \(47^\circ C\) is
The approximate temperature at which the rms speed of Nitrogen gas molecule is \( 500 \text{ ms}^{-1} \). Gas constant \( R=8.314 \text{ J mol}^{-1} \text{K}^{-1} \), Mass number of Nitrogen = 28:
The ratio of velocity of sound to the rms velocity of gas molecules in a diatomic gas is:
If the mean free path of a nitrogen molecule in a vessel containing nitrogen at a pressure of 2.1 atm and a temperature of $27^{\circ}C$ is $\lambda$, then its mean free path at a pressure of 1.65 atm and a temperature of $57^{\circ}C$ is:
The rms speed of oxygen molecule at some temperature is $150 \text{ ms}^{-1}$. Then the rms speed of hydrogen molecule at the same temperature is
The mean free path of a gas molecule is inversely proportional to
The specific heat capacity of a gas at constant pressure ($C_p$) and at constant volume ($C_v$) are related as
The mean free path of a gas molecule is inversely proportional to
At what temperature is the root mean square (rms) speed of oxygen molecules ($O_2$) equal to that of helium molecules ($He$) at $27^\circ\text{C}$? (Given molar mass of $O_2 = 32\text{ g/mol}$, $He = 4\text{ g/mol}$)}
If the volume of a gas is reduced to half then the change in its mean free path is
The density of a gas is 1 molecule cm\(^{-3}\). If the molecular diameter is \(1 \times 10^{-8}\) cm, then the mean free path of the molecules is:
According to the law of equipartition of energy, the molar specific heat of solids at low temperatures is equal to (R = universal gas constant):
A flask of volume 0.1 m\(^3\) contains He (monatomic) and O\(_2\) (diatomic) gases in the ratio 4:1. The flask is maintained at a temperature 27 °C. The ratio of the rms speeds of the He-atoms and O\(_2\)-molecules is:
(Atomic mass of He = 4 amu, and O\(_2\) = 32 amu)
An ideal gas has specific heat capacity at constant pressure \(\dfrac{11}{10}R\). If one mole of this ideal gas at \(125^\circ\text{C}\) does \(83\,\text{J}\) of work adiabatically, then the final temperature of the gas would be \((R=8.3\,\text{J K}^{-1}\text{mol}^{-1})\)
An ideal monoatomic gas of \(1.5\) moles is heated at a constant pressure of \(2\,\text{atm}\) so that its temperature increases from \(30^\circ\text{C}\) to \(130^\circ\text{C}\). Work done by the gas is \((R=8.3\,\text{J mol}^{-1}\text{K}^{-1})\)
