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 ....... $^oC$
$28\,\, gm$ of $N_2$ gas is contained in a flask at a pressure of $10$ atm and at a temperature of $57^o$. It is found that due to leakage in the flask, the pressure is reduced to half and the temperature reduced to $27\,^oC$. The quantity of $N_2$ gas that leaked out is
The pressure and temperature of an ideal gas in a closed vessel are $720\, kPa$ and $40^oC$ respectively. If $\frac{1}{4}^{th}$ of the gas is released from the vessel and the temperature of the remaining gas is raised to $353^oC,$ the final pressure of the gas is ....... $kPa$
