हिन्दीAn ideal gas expands isothermally from \( 10^{-3} \) \( \mathrm{m^3} \) to \( 10^{-2} \) \( \mathrm{m^3} \) at \( 300 \) \( \mathrm{K} \) against a constant pressure of \( 10^5 \) \(\mathrm{Nm^{-2}}\. The work done on the gas is
Correct answer · Option 3
\( -900 \) \( \mathrm{J} \)
Explanation
Work done on the gas \( W = -P \Delta V = -10^5 \times (10^{-2} - 10^{-3}) = -10^5 \times 0.009 = -900 \) \( \mathrm{J} \).
