Which of the following is true for the gaseous state?

$3.2 \, g$ of oxygen gas diffuses in $10 \, minute$. Under similar conditions,$2.8 \, g$ of nitrogen gas will diffuse in ............ $minute$.

$5$ 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

How will the viscosity of a liquid be affected by an increase in temperature?

When the pressure of $1 \ mol$ of ammonia gas changes from $1 \ atm$ to $0.5 \ atm$ at constant temperature,the number of molecules will:

$A$ gaseous mixture of $3$ gases $A$, $B$ and $C$ has a pressure of $10 \,atm$. The total number of moles is $10$. If the partial pressures of gases $A$ and $B$ are $3 \,atm$ and $1 \,atm$ respectively, and the molar mass of gas $C$ is $2 \,g/mol$, calculate the weight of $C$ in the mixture. (in $\,g$)
