$A$ certain mass of gas occupies a volume of $2 \ L$ at $STP$. If the pressure is kept constant,what will be the temperature in $^\circ C$ for the gas to occupy a volume of $4 \ L$?

In the gas equation $PV = nRT$,the universal gas constant $R$ depends on:

In the ideal gas equation,the gas constant $R$ has the dimensions of

Explain the law relating pressure and temperature.

Two closed bulbs of equal volume $V$ containing an ideal gas initially at pressure $P_i$ and temperature $T_1$ are connected through a narrow tube of negligible volume as shown in the figure below. The temperature of one of the bulbs is then raised to $T_2$. The final pressure $P_f$ is:

The pressure exerted by a non-reactive gaseous mixture of $6.4 \ g$ of methane and $8.8 \ g$ of carbon dioxide in a $10 \ L$ vessel at $27^{\circ} C$ is .............$kPa$.
