Homework Assignments and Solutions
Recent Announcements:

need not hand in KK Chapter 14 Problems 5, 6 on Tuesday, but work
them out and check against the solutions to be posted on Friday. They
are included in the final exam material.
2)
Reminder: Of the two extra lectures I gave on phase transition and
modern experiments leading to the discovery of BEC (Nov 28) and phase
transitions in the early universe (Nov 30), you are responsible only
for the material on BEC phase transition.
3)
The final exam will be held Dec 19, 1:303:30 in the classroom (PHY
1402),. You are allowed to bring an additional 8 ½ x 11” formula sheet,
a total of 3.
November 18

For the second midterm exam, one new formula sheet of 8 1/2 x 11'
size written on both sides is allowed in addition to the sheet you
used for the first midterm exam.
 Assignment 7 (and other
old homework) can be picked up anytime outside the TA's office (PHYS
3103).
November 8
1. Slightly revised plan for
lectures in November:
 Nov
7, 9, 14, 16 Chapters 9, 10
 Second Midterm Exam on Tuesday Nov 21 in class.
 Nov 28, 30: Lectures on BEC and superfluids (new
material)
2. Homework Assignment HW8 combined Chapters 9, 10, due
Nov 30
3. Problem Review Session on Thur Nov 16 from 56pm in Room
1402
October 25
Reading for Week
10 (Oct 31, Nov 2) should be Chapter 7 of KK, not Chapter 6.
October 10
Announcement concerning midterm exam:
You are allowed to bring one page of formula sheet 8.5 x 11"
both sides and a nonprogrammable calculator.
Also, HW3 is
available for pickup in my office (3103B) anytime Wednesday afternoon
or Thursday.
October 8
Solutions to homeworks 2
and 3 are now posted. If you have any questions about the solutions,
please let me (Kevin) know – twedt@umd.edu.

> Homework
Assignment 2 : Problem 83 Photon Carnot Engine is counted only as a
bonus problem, meaning you will earn extra point 10 points if
you get it all right but no points deducted if you don’t get it
right or don’t work on it.
It requires prior knowledge of
these two relations for a photon gas (Chapter 4): u (energy
density) = U /V = aT^{4} , s (entropy density) = S/V =
bT^{3} where a, b are related constants.
> Note
also isentropic processes used in KK is defined as processes with
constant entropy. They are equivalent to, via the relation dS = T
dQ, adiabatic processes used in the lectures, defined as
processes with no heat exchange.
