What is the boiling point of $SO_2$ gas (in $K$)?

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

$5$ moles of a gas is allowed to pass through a series of changes as shown in the graph,in a cyclic process. The processes $C \rightarrow A$,$B \rightarrow C$ and $A \rightarrow B$ respectively are

The rate of diffusion of $SO_2$ and $O_2$ are in the ratio:

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

$A$ mixture of equal masses of ethane $(C_2H_6)$ and hydrogen $(H_2)$ is filled in an empty container at $25\,^oC$. What is the fraction of the total pressure exerted by hydrogen?
