For two different gases $X$ and $Y,$ having degrees of freedom $f_1$ and $f_2$ and molar heat capacities at constant volume $C_{v_1}$ and $C_{v_2}$ respectively, for adiabatic process , the $\ln P$ versus $\ln V$ graph is plotted as shown :-
A$f_1 > f_2$
B$f_2 > f_1$
C$C_{v_2} = C_{v_1}$
D$C_{v_1} > C_{v_2}$

A vessel contains a mixture of one mole of oxygen and two moles of nitrogen at $300 K$. The ratio of the average rotational kinetic energy per ${O_2}$ molecule to that per ${N_2}$ molecule is
The temperature of argon, kept in a vessel, is raised by $1^\circ C$ at a constant volume. The total heat supplied to the gas is a combination of translational and rotational energies. Their respective shares are
To raise the temperature of a certain mass of gas by $50^{\circ} C$ at a constant pressure, $160$ calories of heat is required. When the same mass of gas is cooled by $100^{\circ} C$ at constant volume, $240$ calories of heat is released. How many degrees of freedom does each molecule of this gas have (assume gas to be ideal) $?$
A vessel is filled with an ideal gas at a pressure of $10$ atmospheres and temperature ${27}^\circ C$. Half of the mass of the gas is removed from the vessel and temperature of the remaining gas is increased to ${87}^\circ C$. Then the pressure of the gas in the vessel will be ...... $atm$
A horizontal uniform glass tube of $100 \,cm$, length sealed at both ends contain $10 \,cm$ mercury column in the middle. The temperature and pressure of air on either side of mercury column are respectively $81°C$ and $76\, cm$ of mercury. If the air column at one end is kept at $0°C$ and the other end at $273°C$, the pressure of air which is at $0°C$ is (in $cm$ of $Hg$)
An ideal gas is trapped inside a test tube of cross-sectional area $20 \times 10^{-6} \,\,m^2$ as shown in the figure. The gas occupies a height $L_1$ at the bottom of the tube and is separated from air at atmospheric pressure by a mercury column of mass $0.002\,\, kg$. If the tube is quickly turned isothermally, upside down so that $L_2$ mercury column encloses the gas from below. The gas now occupies height $L_1$ in the tube. The ratio $L_1$ is [Take atmospheric pressure $= 10^5 Nm^{-2}]$
Five moles of helium are mixed with two moles of hydrogen to form a mixture. Take molar mass of helium $M_1=4\ g$ and that of hydrogen $M_2=2\ g$ The equivalent molar mass of the mixture is
A thermally insulated vessel contains an ideal gas of molecular mass $M$ and ratio of specific heats $1.4$. Vessel is moving with speed $v$ and is suddenly brought to rest. Assuming no heat is lost to the surrounding and vessel temperature of the gas increases by ... ( $R =$ universal gas constant )
Two spherical vessel of equal volume, are connected by a n arrow tube. The apparatus contains an ideal gas at one atmosphere and $300K$. Now if one vessel is immersed in a bath of constant temperature $600K$ and the other in a bath of constant temperature $300K$. Then the common pressure will be ...... $atm$
