In the experimental process, the ideal gas is expanded isothermally from an initial pressure of \(0.8\,\mathrm{MPa}\) and volume of \(V_1=0.3\,\mathrm{m}^3\) to a final volume of \(V_2=1.2\,\mathrm{m}^3\). Find a work done by the gas in the given process. Hint: During isothermal expansion, both pressure \(p\) and volume \(V\) change along an isotherm with a constant \(pV\) product. The work \(W\) done by a gas is defined as \(W=\int_{V_1}^{V_2}p\mathrm{d}V\).
\( W\doteq 333\,\mathrm{kJ}\)
\( W \doteq 216\,\mathrm{kJ}\)
\( W \doteq 720\,\mathrm{kJ}\)
\( W \doteq 178\,\mathrm{kJ}\)
