Consider two boxes, each of which is filled with ideal gases. Consider that the two boxes are combined. 1. Under what condition or conditions will the volume and energy be extensive? 2. Based on the above answer, show that entropy is also extensive. Hint: The Entropy of an ideal gas is (as you know by now) V NA +5N/2 S/kg Nlog(; = anaa + aran-[ S, V, E, N S2, V2, E2, N2 S,V,E,N
