The correct option for free expansion of an ideal gas under adiabatic condition is : (1) q > 0, ΔT > 0 and w > 0 (2) q = 0, ΔT = 0 and w = 0 (3) q = 0, ΔT < 0 and w > 0 (4) q < 0, ΔT = 0 and w = 0 |

Answer» (2) q = 0, ΔT = 0 and w = 0 free expansion of ideal gas Pext = 0 Wpv = 0 q = 0 (adiabatic process) ΔE = q + w ΔE = 0 ΔE = nCvm ΔT = 0 q = 0, ΔT = 0, w = 0 |
