The critical temperature of some gases are: Methane 190K, ammonia 405K, carbon dioxide 304K, n-butane 425K and dihydrogen 33K. The gas that is adsorbed to the maximum extent on 1g of activated charcoal at a given temperature is

A gas mixture contains 50% helium and 50% methane by volume. What is the percent by weight of methane in the mixture ?

In an ionized gas the mobile charge carriers are

Air at sea level is dense. This is a practical implimentation of:

The expression for van der Waals equation for the gas law is

Two vessels of volumes $16.4\, L$ and $5\,L$ contain two ideal gases of molecular existence at the respective temperature of $27^?C$ and $227^?C$ and exert $1.5$ and $4.1$ atmospheres respectively. The ratio of the number of molecules of the former to that of the latter is

An evacuated glass vessel weighs $50 \,g$ when empty, $144.0\, g$ when filled with a liquid of density $0.47 \,g \,ml^{-1}$ and $50.5\, g$ when filled with an ideal gas at $760 \,mm \,Hg$ at $300\, K$. The molar mass of the ideal gas is: ($R= 0.0821\, L$ atm. $K^{-1} \,mol^{-1}$)
