3. (a) How many paths are there from the point (0, 0) to the point (110, 111) in the plane such that each
step either consists of going one unit up or one unit to the right? (b) How many paths are the

The logarithms are in base 10, R is expressed in ohms, and T in Kelvin. a) In a liquid helium cryostat, the
resistance is measured to be 218 ohms. What is the temperature? b) Make a loglog graph of R
Imagine that we are given the function A(x,y) = 2xy2 and are instructed to integrate it with respect to x,
from x = 0 to x = 1. This presents no difficulty: Z 1 0 A(x,y) dx = x 2 y 2 1 0 = y 2 . It is
The sign of the work done depends on the direction in which the piston is moved. The work done on the
system will be positive if the displacement is in the same direction as that of the applied force
We begin this interlude by introducing the twodimensional plane with coordinates x and y. To denote an
infinitesimal displacement in the x direction we use dx, and dy denotes an infinitesimal displac
The general idea is that microscopically, temperature is defined to be a measure of the kinetic energy of
our gas molecules. More precisely, temperature is defined by the statement 1 2mv2 = 3 2 kT, wh
A thermodynamic system is always confined within some boundary. Outside this boundary is the
systems surroundings. The combination system + boundary + surroundings is called the universe. (The
