-
fired
powerplants
,
the
____________________
energy
in
the
coal
goes
under
a
series
of
transformations
,
During
the
process
of
____________________
,
the
chemical
energy
in
the
coal
gets
converted
into
____________________
energy
.
Then
through
the
heat
exchanger
,
the
thermal
energy
of
the
exhaust
gases
gets
converted
into
____________________
energy
of
____________________
.
After
that
in
the
turbine
,
the
thermal
energy
of
____________________
gets
converted
into
____________________
energy
.
Finally
,
with
the
help
of
a
____________________
,
the
____________________
energy
gets
converted
into
____________________
energy
