371590 Ten moles of an ideal gas at constant temperature 500 K is compressed from 50 L to \({5 L}\). Work done in the process is (Given, \({\left.R=8.31 J-{mol}^{-1}-K^{-1}\right)}\)

1 \({-1.2 \times 10^{4} J}\)
2 \({-2.4 \times 10^{4} J}\)
3 \({-4.8 \times 10^{4} {~J}}\)

371591 Statement A :
In an isothermal expansion, the gas absorbs heat and does work while in an isothermal compression, work is done on the gas by the environment and heat is released.
Statement B :
In an isothermal process, there is no change in internal energy of an ideal gas.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.

371592 One mole of \({O_2}\) gas having a volume equal to \(22.4\,liters\) at \(0^\circ C\) and 1 atomspheric pressure is compressed isothermally so that its volume reduces to \(11.2\,liters\). The work done in this process is

1 \(1728\;J\)
2 \(1672.5\;J\)
3 \( - 1572.5\;J\)
4 \( - 1728\;J\)
