An electron tube was sealed off during manufacture at a pressure of $1.2 \times {10^{ - 7}}$ $mm$ of mercury at $27°C.$ Its volume is $100\, cm^3$. The number of molecules that remain in the tube is
A $15\,g$ mass of nitrogen gas is enclosed in a vessel at a temperature $27\,^oC.$ Amount of heat transferred to the gas, so that rms velocity of molecules is doubled, is about ...... $kJ$ [Take $R = 8.3\,J/K\,mole$ ]
At a certain temperature, the $r.m.s.$ velocity for ${O_2}$ is $400\, m/sec.$ At the same temperature, the $r.m.s.$ velocity for ${H_2}$ molecules will be ....... $m/sec$
