A gas bulb of 1L capacity contains 2.0×1011 molecules of nitrogen exerting a pressure of 7.57×103Nm−2. Calculate the root mean square (rms) speed and the temperature of the gas molecules. If the ratio of the most probable speed to the root mean square is 0.82, calculate the most probable speed for these molecules at this temperature.
Which of the following graphs is not a straight line for an ideal gas?
If a gas expended at constant temperature
The surface tension of which of the following liquid is maximum?
A closed vessel with rigid walls contains 1 mole of .92238U and 1 mole of air at 298K. Considering complete decay of .92238U to .82206Pbthe ratio of the final pressure to the initial pressure of the system at 298K is
The rate of diffusion of a gas is………….proportional to both ……….. And square root of molecular mass.
The composition of the equilibrium mixture (`Cl_(2)` `2Cl`) , which is attained at `1200^(@)C`, is determined by measuring the rate of effusion through a pin hole. It is observed that a `1.80 mm Hg` pressure, the mixture effuses `1.16 times` as fact as krypton effuses under the same conditions. Calculate the fraction of chlorine molecules dissociated into atoms (atomic weight of `Kr` is `84`).
Why at extremely low pressures, the real gases obey the ideal gas equation?
