$125\, ml$ of gas $A$ at $0.60$ atmosphere and $150\, ml$ of gas $B$ at $0.80$ atmosphere pressure at same temperature is filled in a vessel of $1$ litre volume. What will be the total pressure of mixture at the same temperature ............... $\mathrm{atmosphere}$
Two thermodynamical process are shown in the figure. The molar heat capacity for process $A$ and $B$ are $C_A$ and $C_B$. The molar heat capacity at constant pressure and constant volume are represented by $C_P$ and $C_V$, respectively. Choose the correct statement.
To what temperature should the hydrogen at $327°C$ be cooled at constant pressure, so that the root mean square velocity of its molecules become half of its previous value ....... $^oC$
The molecules of a given mass of a gas have $r.m.s.$ velocity of $200 \,m s^{-1}$ at $27^o C$ and $1.0 \times 10^5 \,Nm^{-2}$ pressure. When the temperature and pressure of the gas are respectively, $127^o C$ and $0.05 \times 10^5 \,Nm^{-2},$ the $r.m.s.$ velocity of its molecules in $m s^{-1}$ is
Vessel $A$ is filled with hydrogen while vessel $B,$ whose volume is twice that of $A,$ is filled with the same mass of oxygen at the same temperature. The ratio of the mean kinetic energies of hydrogen and oxygen is
The root mean square speed of hydrogen molecules at $300$ $K$ is $1930\, m/s.$ Then the root mean square speed of oxygen molecules at $900\, K$ will be ....... $m/s$
