If the volume of a gas is $V \ L$ at $P \ atm$ pressure and $27 \ ^oC$ temperature,what will be the volume of the gas at $-173 \ ^oC$ temperature and $P \ atm$ pressure if the amount of gas is doubled?

The value of the universal gas constant $R$ is the same for all gases. What is its physical significance?

Choose the correct option for the total pressure (in $atm$) in a mixture of $4 \ g$ $O_2$ and $2 \ g$ $H_2$ confined in a total volume of $1 \ L$ at $0^{\circ} C$ is :
$\left[ \text{Given } R = 0.082 \ L \ atm \ mol^{-1} \ K^{-1}, T = 273 \ K \right]$

If pressure becomes double at the same absolute temperature on $2 \ L$ $CO_2$,then the volume of $CO_2$ becomes ............ $L$.

For the same mass of two different ideal gases of molecular weights $M_{1}$ and $M_{2}$,plots of $\log V$ vs $\log p$ at a given constant temperature are shown. Identify the correct option.

If $500 \ mL$ of gas $A$ at $1000 \ torr$ and $1000 \ mL$ of gas $B$ at $800 \ torr$ are taken in a $2 \ L$ container,the final pressure is .......... $torr$.
