Practice question
Question
For an ideal gas compressed reversibly and isothermally from 15 L to 3 L at 350 K, calculate the work done. ( R = 8.314 J/mol·K , 1 mol gas)
Explanation
For reversible isothermal compression, w = -nRT ln(V₂/V₁) = -1 × 8.314 × 350 × ln(3/15) = -2909.9 × (-1.6094) ≈ 4685 J .
