When $48 \, L$ of dry $N_2$ gas at $27 \, ^oC$ is passed through $36 \, g$ of water,the weight of water decreases by $1.20 \, g$. What is the vapor pressure of water in $atm$?

Which one of the following equations represents the variation of viscosity coefficient $(\eta)$ with temperature $(T)$?

The variation of pressure with volume of a gas at different temperatures can be graphically represented as shown in the figure. On the basis of this graph,answer the following questions:
$(i)$ How will the volume of a gas change if its pressure is increased at constant temperature?
$(ii)$ At a constant pressure,how will the volume of a gas change if the temperature is increased from $200 \ K$ to $400 \ K$?

Two statements are given below.
Statement-$I$: The ratio of the molar volume of a gas to that of an ideal gas at constant temperature and pressure is called the compressibility factor.
Statement-$II$: The $RMS$ velocity of a gas is directly proportional to the square root of $T(K)$.
The correct answer is

Which one of the following statements is false?

Equal masses of ethyne $(C_2H_2)$ and benzene $(C_6H_6)$ are taken in a flask at $400 \ K$. If the partial pressure of benzene is $600 \ torr$,what will be the total pressure of the gaseous mixture in $torr$?
