Oxygen
(),
gas atand 1.0 atm pressure
is confined to a cubical box 25 cm
on a side. We have to calculate the change in gravitational potential
energy of a mole of oxygen molecules in falling the height of the box
to the total kinetic energy of the molecules.
The kinetic energy of one
mole of molecules at temperature T K is
where
is the Avogadro number and
is the Boltzmann constant. Temperature of
is 288.16 K. Therefore,
Molecular
weight of
is,
therefore the change in gravitational potential energy of one mole
of oxygen molecules when they drop in height by
25 cm will be
Ratio of
change in gravitational potential energy of one mole of oxygen
molecule in a vertical distance of 25 cm to the thermal energy at
