MCQ (Single Correct Answer)
The compressibility factor for a van der Waal gas at high pressure is
The root mean square (rms) speed of X$$_2$$ gas is x m/s at a given temperature. When the temperature is doubled, the X$$_2$$ molecules dissociated completely into atoms. The root mean square speed of the sample of gas then becomes (in m/s)
Case - 1 : An ideal gas of molecular weight M at temperature T.
Case - 2 : Another ideal gas of molecular weight 2M at temperature T/2.
Identify the correct statement in context of above two cases.
The average speed of H2 at T1K is equal to that of O2 at T2K. The ratio T1 : T2 is
Avogadro's law is valid for
Let (Crms)H2 is the r.m.s. speed of H2 at 150 K. At what temperature, the most probable speed of helium [Cmp)He] will be half of (Crms)H2 ?
For same mass of two different ideal gases of molecular weights M1 and M2, Plots of log V vs log p at a given constant temperature are shown. Identify the correct option.
