Answer 1

When total energy U = 6 epsilon and maximum energy level 4 epsilon The no. of microstate which satisfying total energy is 6 epsilon is given by pi_1 = 4 So, the entropy of this system S_1 = Km pi_1 = Km4 when the total energy U = 7 epsilon and maximum energy level 5 epsilon \r\n The no. of microstate which satisfying the total energy is 7 epsilon is given by pi_2 = 7 The entropy of this system S_2 = Km pi_2 = Km7 Therefore, the change in entropy delta S_2 - S_1 = Km7 - Km4 delta S = Km 7/4 = 1.38 times 10^-23 times m 7/4 J/K delta S = 0.77 times 10^-23 J/K \r\n ln A + ln B = ln (AB) ln A - ln B = ln (A/B)
$lnA+lnB=ln(AB)$

$lnA-lnB=ln(\frac{A}{B})$
