3.0\,\text{mol}

sample of an ideal gas at

400\,\text{K}

occupies

0.025\,\text{m}^3

. The gas undergoes an isothermal expansion until its pressure falls to

8.0\times10^{4}\,\text{Pa}

. (i) Calculate the initial pressure of the gas. (ii) Determine the final volume attained after expansion. (iii) Find the work done by the gas during this expansion.
