One mole of an ideal monoatomic gas is compressed isothermally in a rigid vessel to double its pressure at room temperature,$27\,^{\circ}C$. The work done on the gas will be

In an isothermal reversible expansion,if the volume of $96\, g$ of oxygen at $27^{\circ}C$ is increased from $70\, L$ to $140\, L$,then the work done by the gas will be

Can two isothermal curves intersect each other?

Select the $WRONG$ statement from the following. For an isothermal process:

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:

The internal energy of an ideal gas increases during an isothermal process when the gas is
