A gaseous mixture contains equal number of hydrogen and nitrogen molecules. Specific heat measurements on this mixture at temperatures below $100\, K$ would indicate that the value of $\gamma $ (ratio of specific heats) for this mixture is
Pressure versus temperature graph of an ideal gas at constant volume $V$ of an ideal gas is shown by the straight line $A$. Now mass of the gas is doubled and the volume is halved, then the corresponding pressure versus temperature graph will be shown by the line
The value of densities of two diatomic gases at constant temperature and pressure are ${d_1}$ and ${d_2}$, then the ratio of speed of sound in these gases will be
If one mole of the polyatomic gas is having two vibrational modes and $\beta$ is the ratio of molar specific heats for polyatomic gas $\left(\beta=\frac{ C _{ P }}{ C _{ v }}\right)$ then the value of $\beta$ is:
To what temperature should the hydrogen at room temperature $(27°C)$ be heated at constant pressure so that the $R.M.S.$ velocity of its molecules becomes double of its previous value ....... $^oC$
Which of the following plots represents schematically the dependence of the time period of a pendulum, if measured and plotted as a function of the amplitude of its oscillations? (Note amplitude need not be small)
