For crystalline KCl (a) Calculate the electrostatic potential
energy of attraction in KCl; (b) determine the value of n in the
exclusion principle energy equation.
The question is: How to calculate
the energy of electrostatic field of a newly created
particle.
The usual formula involves integration 'all over space'.
According to GR I believe that 'all over space' means the interior
volume with radius c*t_now, where t_now is the lifetime of the
particle at the time of calculation and c is the light speed.
Thus the energy stored in the field is a quantity dependent on
time evolution.
this is a clarification of the question...
a. Calculate the cell potential for the electrolysis of
water.
b. Discuss whether energy is created or produced in the
electrolysis of water or in redox reactions. How does the energy
used to charge the fuel cell compare to the energy available for
use?

Calculate the heat/mole KCl when KCl is dissolved in water if
3.00 grams of KCl changes the temperature of 301 mL of water from

b. Compare what happens to potential energy, kinetic energy, and
total energy as the skater moves up and down the track. What
general statement can you make about the relationship between

c. Notice that the bar entitled “Thermal” energy does not
deviate from zero. This represents an energy that is transformed
into "heat" energy. What must be true of this skate park for this
