Considering the gases to be ideal, the value of $\gamma  = \frac{{{C_p}}}{{{C_v}}}$ for a gaseous mixture consisting of $3\ moles$ of carbon dioxide and $2\ moles$ of oxygen will be $({\gamma _{{O_2}}} = 1.4\,,{\gamma _{C{O_2}}} = 1.3)$

The root mean-square speed $(rms)$ of oxygen molecules $(O_2)$ at a certain absolute temperature is $\upsilon $ . If the temperature is doubled and the oxygen gas dissociates into atomic oxygen, the $rms$ speed would be

In a thermally isolated system, two boxes filled with an ideal gas are connected by a valve. When the valve is in closed position, states of the box $1$ and $2$ respectively, are ( $1 \,atm , V, T)$ and $(0.5 \,atm , 4 V, T)$. When the valve is opened, then the final pressure of the system is approximately …………… $atm$

At a given temperature, the pressure of an ideal gas of density $\rho $ is proportional to

Pressure of an ideal gas is increased by keeping temperature constant. What is the effect on kinetic energy of molecules ?
