  • Kapil prajapat thankyou
    free expansion means temperature is same not adiabatic.

    Change in entropy = ΔS = Nk × ln(Vf/Vi) N = number of atoms (1 mole equals Avogadro’s number) = 6.022 × 10^23 k = Boltzmann constant = 1.3806 × 10^-23 Vf = final volume = 2 Vi ...

    free expansion = adiabatic process. Am I right ??? then ∆s = 0
