$A$ $10 \ g$ of a gas at atmospheric pressure is cooled from $273 \ ^oC$ to $0 \ ^oC$ keeping the volume constant,its pressure would become ............. $atm$.

If $P$,$V$,$M$,$T$ and $R$ are pressure,volume,molar mass,temperature and gas constant respectively,then for an ideal gas,the density is given by

At a given temperature,the density of gas $x$ is twice that of gas $y$. The molar mass of $x$ is one-third of the molar mass of $y$. What is the ratio of their pressures $(P_x / P_y)$?

Which amongst the following options is the correct graphical representation of Boyle's law?

The initial volume of a gas cylinder is $750.0 \ mL$. If the pressure of gas inside the cylinder changes from $840.0 \ mm \ Hg$ to $360.0 \ mm \ Hg$,what will be the final volume of the gas (in $L$)?

The volume occupied by $4.75 \, g$ of acetylene gas at $50^{\circ} C$ and $740 \, mm \, Hg$ pressure is ....... $L$.
