Kinetic Model and Pressure.
The force on a wall can be calculated using Newtons Second Law of Motion:
force, F, equals the rate of change of momentum, F = p/t.
Each molecule of mass m with an x-component of its
velocity vx, upon colliding with the wall, c

Classical Integrated Average Relationship
If a classical system has a coordinate x, the probability of finding the
system at any point x is given by the probability distribution function
P(x ), then the average value of a parameter A( x ) is given by the
Chapter 3. The Second Law
The First Law tells us that the energy of the universe is constant - energy
is conserved but it says nothing about the spontaneity of physical and
