148248 When a gas closed in a closed vessel was heated so as to increase its temperature by $5^{\circ} \mathrm{C}$, its pressure was seen to have increased by $1 \%$. The initial temperature of the gas was nearly

148249 Two identical containers $A$ and $B$ with frictionless pistons contain the same ideal gas at the same temperature and the same volume $V$. The mass of the gas in $A$ is $M_{A}$ and that in $B$ is $M_{B}$. The gas in each container is now allowed to expand isothermally to the same final volume $2 \mathrm{~V}$. The changes in the pressure in $A$ and $B$ are to be found $\Delta p$ and $1.5 \Delta p$ respectively, then relation for masses will be

1 $4 \mathrm{~m}_{\mathrm{A}}=9 \mathrm{~m}_{\mathrm{B}}$
2 $2 \mathrm{~m}_{\mathrm{A}}=3 \mathrm{~m}_{\mathrm{B}}$
