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
