${\mathrm{N}}_2+3{\mathrm{H}}_2⟶2{\mathrm{NH}}_3.$ $1$ mole ${\mathrm{N}}_2$ and $4$ moles ${\mathrm{H}}_2$ are taken in $15 \mathrm{L}$ flask at $27°\mathrm{C}$. After complete conversion of ${\mathrm{N}}_2$ into ${\mathrm{NH}}_3, 5 \mathrm{L}$ of ${\mathrm{H}}_2\mathrm{O}$ is added. Pressure set up in the flask is

Which of the following is not the correct set of pressure and volume at constant temperature and constant moles of gas?

The volume of a gas increases by a factor of $2$ while the pressure decreases by a factor of $3$. Given that the number of moles is unaffected, the factor by which the temperature changes is

A quantity of gas is collected in a graduated tube over the mercury. The volume of gas at $18°\mathrm{C}$ is $50.0 \mathrm{mL}$ and the level of mercury in the tube is $100$torr above the outside mercury level. The barometer reads $750$ Torr. Hence, volume at STP is approximately.

In van der Waal's equation of state for a non-ideal gas, the term that accounts for intermolecular forces is

An open flask containing air is heated from $300 \mathrm{K}$ to $500 \mathrm{K}.$ What percentage of air will be escaped to the atmosphere, if pressure is keeping constant?

A gaseous mixture of three gases $\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$ has a pressure of $10$ atm. The total number of moles of all the gases is $10$. If the partial pressures of $\mathrm{A}$ and $\mathrm{B}$ are $3.0$and $1.0$ atm respectively and if $\text{'}\mathrm{C}\text{'}$ has mol. weight of $2.0$ . What is the weight of  $\text{'}\mathrm{C}\text{'}$ in $\mathrm{g}$ present in the mixture.

Viscosity is a measure of resistance of a liquid to flow and viscosity-
