The equation of state of a gas is given by $\left( {P + \frac{{a{T^2}}}{V}} \right)\,{V^c} = (RT + b)$, where $a, b, c$ and $R$ are constants. The isotherms can be represented by $P = A{V^m} - B{V^n}$, where $A$ and $B$ depend only on temperature then

$\frac{1}{2} $ mole of helium gas is contained in a container at $S.T.P.$ The heat energy needed to double the pressure of the gas, keeping the volume constant (specific heat of the gas $ = 3\,J\,g{m^{ - 1}}\,{K^{ - 1}})$ is ...... $J$
A very tall vertical cylinder is filled with a gas of molar mass $M$ under isothermal conditions at temperature $T.$ The density and pressure of the gas at the base of the container is $\rho_0$ and $p_0$, respectively Choose the correct statement$(s)$
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
If $10^{22}$gas molecules each of mass $10^{-26}\, kg$ collide with a surface (perpendicular to it)elastically per second over an area $1\, m^2$with a speed $10^4\,m/s$, the pressure exerted by the gas molecules will be of the order of
Consider a gas for which diameter of molecules is $\sigma $ , the gas is at a pressure $P$ and temperature $T$ and $N_a =$ avagodro’s number. The mean free path along $x$ axis is
For a given gas at $1\,atm$ pressure, $rms$ speed of the molecules is $200\,m/s$ at $127\,^oC.$ At $2\,atm$ pressure and at $227\,^oC,$ the $rms$ speed of the molecules will be
