$A$ certain amount of heat supplied to an ideal gas under isothermal conditions will result in:

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 cylinder is now allowed to expand isothermally to the same final volume $2V$. The changes in the pressure in $A$ and $B$ are found to be $\Delta P$ and $1.5 \Delta P$ respectively. Then:

In an isothermal change,the change in pressure and volume of a gas can be represented for three different temperatures $T_3 > T_2 > T_1$ as:

One mole of an ideal gas at $27^{\circ} {C}$ is taken from $A$ to $B$ as shown in the given $PV$ indicator diagram. The work done by the system will be $...... \times 10^{-1} \, {J}$.
[Given: $R = 8.3 \, {J} / \text{mole} \cdot {K}, \ln 2 = 0.6931$] (Round off to the nearest integer)

If the pressure of an ideal gas is decreased by $10 \%$ isothermally,then its volume will

The volume of an ideal gas is $1 \, L$ and its pressure is equal to $72 \, cm$ of mercury column. The volume of the gas is made $900 \, cm^3$ by compressing it isothermally. The increase in the pressure of the gas will be ...... $cm$ of mercury.
