Object A and object B are two identical microscopic objects. Thetable below shows the number of ways to arrange energy in one ofthese objects, as a function of the amount of energy in theobject.
E (joules) 4e-21 6e-21 8e-21 1e-20 1.2e-20 1.4e-20 1.6e-20
# ways 6 20 37 60 90 122 148
When there are 1.4e-20 joules of energy in object A, what is theentropy of this object?
SA = ? J/K
When there are 4e-21 joules of energy in object B, what is theentropy of this object?
SB = ? J/K
Now the two objects are placed in contact with each other. At thismoment, before there is time for any energy flow between theobjects, what is the entropy of the combined system of objects Aand B?
SAB = ? J/K
