138996 An ideal gas at temperature $T$, pressure $p$ occupies a volume $V$. If its temperature is halved and pressure doubled, what is its new volume?

138998 A cyclic process on 1 mole of an ideal gas is shown in the figure. The temperatures of the gas at points $A$ and $B$ are respectively $200 \mathrm{~K}$ and $400 \mathrm{~K}$. A total of $200 \mathrm{~J}$ of heat is taken out from the system in the process. What is the work done by the gas in the process $B \rightarrow C$ ? (Let $\mathrm{R}=8.3 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}$ )

138999 Molecular weight of oxygen is 32 amu. At STP, volume of $1 \mathrm{gm}$ of oxygen is $700 \mathrm{~cm}^{3}$. What is the value of gas constant $R$ ?

139000 A thermally insulated piston divides a container into a two compartments. The volume, temperature and pressure in the right compartment are $2 \mathrm{~V}, \mathrm{~T}$ and $2 \mathrm{P}$, while in the left compartment the corresponding parameters are $V, T$ and $P$. Then the ratio of number of molecules in the right compartment to that in the left compartment is
