Question
Chapter 6, Problem 6.8E
Interpretation Introduction
Interpretation: The different algebraically equivalent way for the given equation 6.2 is to be stated. The reason as to why the stated expression is an equivalent expression is to be explained.
Concept introduction: The expressions are said to be equivalent when they have the same value, but they look different from each other. Equivalent expressions always give the same value on simplification.

After you watch for a few minutes, you'll notice that as
the atoms get very close to one another, the repulsive
force increases (symbolized by green force arrows that
point away from each other). This increase in the
repulsive force causes the potential energy of the
system (on the potential energy curve) to increase.
This is reproduced on the figure below, with specific
reference to the circled region.

(A) if both sentences are true, (B) if both sentences are false, (C) if the first sentence is true but the second is false, and (D) if the first sentence is false but the second is true.
1. Water appears in nature in all three common states of matter. Water is a tasteless, odorless liquid at standard temperature and pressure.
2. The addition of salt in the distilling mixture made the water impure and saline. The addition of 5 drops of the silver nitrate solution into the distillate determines whether the distillate is impure or pure water.
3. The ideal electrical conductivity of totally pure water is 0.055 microSiemens, whereas typical deionized water has an electrical conductivity of 0.1 microSiemens. The freezing point of water at 1 atm is 100degC.
4. From the air, oxygen can slowly diffuse across the water’s surface from the surrounding atmosphere, or be mixed in quickly through aeration, whether natural or man-made. The aeration of water can be caused by wind (creating waves),…
The diagram below shows a system that is made up of 3 molecules (labeled A, B, and C) that contains a total of 4
units of energy. Assuming that no molecule can have 0 energy associated with it, and that only integral amounts
of units of energy are allowed (energy = 1 or energy = 2 is allowed, but energy = 1.5 is not). In the left-most
diagram, one possible way of distributing the four units of energy among these three molecules is presented. This
distribution is represented as: (1, 1, 2).

a. Show explicitly that a total of 4 units of energy are present in the left-most diagram.
b. Explain why (1, 3, 0) is not an allowed distribution for this system.
