![If this energy is transferred to the atoms in the cathode and cause excessive heating and possible
explosion. We call this a "short circuit." You prevent this by by allowing the electrons to pass through an
electrical resistor, something like a light bulb, a motor, or a heater to use up the energy before the
electrons make it to the cathode. If the heater were dipped in water, it would be enough to heat
g of water from room temperature (25°C) to its boiling point (100°C). The energy is also
enough to turn a motor in order to lift a
kg object to a height of one meter; the work (in
Joules) needed to lift an object to a height h is mgh, where m is the mass in kg, g is the acceleration due to
gravity (9.80 m/s2), and h is in meters](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F48e43d24-e797-4c18-89f0-87785ffa58f5%2F2dab8ebb-ecd5-4729-b3f7-6139e0170166%2F32xh7ev_processed.jpeg&w=3840&q=75)

What would be the total kinetic energy gained by a mole of electrons? First, let us calculate the charge of
one mole of electrons; this is called Faraday's constant. We just multiply the charge one electron by
Avogadro's number (NA = 6.022x103 mol ').
F= (N (e) =
C mol (three significant digits)
KE gained by of one mole of electrons = NA (e) (Ece) Or (F)(Ec)
J/mol (three significant digits)
The kinetic energy that would be gained by n moles of electrons is (n)(FXEc«t}. A typical 9-V battery can
put out a current of 0.58 A. One ampere (A) is equivalent a Coulomb per second. How much KE will be
gained by electrons in one minute? First we calculate n, the moles of electrons in one minute.
