  • A mixture of three gases X (density 1.0), Y (density 0.2), and Z (density 0.4) is enclosed in a vessel at constant temperature. When the equilibrium is established, the gas/gases:

  • When an ideal gas undergoes unrestricted expansion, no cooling occurs because the molecules:

  • Which of the following mixture of gases at room temperature would not follow Dalton's law of partial pressures?

  • The root mean square velocity of an ideal gas at constant pressure, varies with density (d) as :

  • Equal masses of methane and oxygen are mixed in an empty container at 25C25^\circ C. The fraction of the total pressure exerted by oxygen is :

  • The molecular velocity of any gas is :

  • Under critical state of a gas, for one mole of a gas, compressibility factor is :

  • A 100 mL flask contained H2H_2, at 200 Torr and a 200 mL flask contained He at 100 Torr. The two 2 flask were then connected so that each gas filled their combined volume. Assuming no change in temperature, total pressure is :

  • The temperature at which N2N_2 molecules would have the same average speed as that of helium atoms at 300K is :

  • At 0C 0^\circ C and one atm pressure, a gas occupies 100 cc. If the pressure is increased to one and a half-time and temperature is increased by one-third of given temperature, then final volume of the gas will be
