Who among the following scientists has not done any important work on gases?

$A$ sample of air contains $N_2$ and $O_2$ saturated with water vapor,with a total pressure of $640 \ torr$. If the water vapor pressure is $40 \ torr$ and the molar ratio of $N_2$ to $O_2$ is $3 : 1$,what is the partial pressure of $N_2$ in the sample in $torr$?

The ratio $\gamma$ for inert gases is

Which physical property decreases with an increase in intermolecular forces?

Which one is not a correct mathematical equation for Dalton's Law of partial pressure? Here $p =$ total pressure of the gaseous mixture.

$X \ mL$ of $H_2$ gas effuse through a hole in a container in $5 \ seconds$. The time taken for the effusion of the same volume of the gas specified below under identical conditions is
