Consider the coin diagram. We see that for the ‘four heads’ state, there are w = 1 microstates. For this question, we will call ‘two heads, two tails’ state 1, and ‘one head, three tails’ state 2. a) For state 1, find w.
b) What is the entropy of the system for state 1?
c) What is the entropy of the system for state 2?
d) Imagine now that we throw the coins and they land in state 1. We then rearrange them into state 2.
i. What is the change in entropy here?
ii. Which law does this violate?
iii. What went wrong? What must we also consider?

An isolated conducting spherical shell carries a positive charge. part a which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? electric potential inside the shell is constant and outside the shell is changing as 1/r2 both the electric potential and the electric field does change with r inside and outside the spherical shell electric potential inside and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is equal to zero electric field inside and outside the shell is constant (does not change with the position r), but is not equal to zero electric field inside and outside the shell is changing as 1/r (where r is the distance from the center of the sphere) electric field inside is equal to zero and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is changing as 1/r electric field inside and outside the shell is changing as 1/r2 electric field inside is equal to zero and outside the shell is changing as 1/r2 electric field inside and outside the shell is zero electric field inside is constant and outside the shell is changing as 1/r
