DApproximately equal and its value is $5\, cal/mole/°C$
d ${C_V}$(Bi-atomic) $= \frac{5}{2}R$ $Joule/mol/°C$ $ = \frac{5}{2}\frac{R}{J}$
$\approx 5$ $\frac{{cal}}{{mol - ^\circ C}}$

A cylinder contains hydrogen gas at pressure of $249\; kPa$ and temperature $27^{\circ} C$. Its density is$.............kg / m ^{3}$ $\left( R =8.3\, J\, mol ^{-1} K ^{-1}\right)$
$\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 ...... $J$
$2\, moles$ of helium gas is mixed with $3\, moles$ of hydrogen molecules (taken to be rigid). What is the molar specific heat of mixture at constant volume ....... $J/mol\, K$ ? $(R = 8.3\, J/mol\, K)$
A gas at the temperature $250\, K$ is contained in a closed vessel. If the gas is heated through $1\,K,$ then the percentage increase in its pressure will be .... $\%$
Consider a gas with density $\rho $ and $\bar c$ as the root mean square velocity of its molecules contained in a volume. If the system moves as whole with velocity $v,$ then the pressure exerted by the gas is
A mixture of $2\, moles$ of helium gas (atomic mass $= 4\, u$), and $1\, mole$ of argon gas (atomic mass $= 40\, u$) is kept at $300\, K$ in a container. The ratio of their rms speeds $\left[ {\frac{{{V_{rms}}{\rm{(helium)}}}}{{{V_{rms}}{\rm{(argon)}}}}} \right]$, is close to
An ideal gas $(\gamma = 1.5)$ is expanded adiabatically. How many times has the gas to be expanded to reduce the root mean square velocity of molecules $2.0$ times
