The ratio of rates of diffusion of gases $X$ and $Y$ of molecular weights $36$ and $64$ is

The ratio of rates of diffusion of gases $A$ and $B$ is $1 : 0.707$. If the molecular weight of $B$ is $32$,the molecular weight of $A$ is

Calculate the partial pressure exerted by dioxygen from a mixture of $32 \ g$ $O_2$,$80 \ g$ $Ar$ (molar mass $40 \ g/mol$) and $4 \ g$ dihydrogen $(P_{\text{total}} = 10 \ bar)$. (in $bar$)

What is the reason that a liquid can flow from one container to another at a specific temperature?

The temperature at which the vapour pressure of a liquid becomes equal to the atmospheric pressure is known as:

The gaseous state is characterized by which of the following properties?
