Question

The correct option for free expansion of an ideal gas under adiabatic condition is:

(1) q = 0, $\Delta$T = 0 and w = 0

(2) q = 0, $\Delta$T < 0 and w > 0

(3) q < 0, $\Delta$T = 0 and w = 0

(4) q > 0, $\Delta$T > 0 and w > 0

Factual question

Answer 1

Ans: (1) q = 0, ΔT = 0 and w = 0

Sol: For adiabatic process q=0, for free expansion w=0 and there will be no change in temperature gradient (ΔT=0).
