2. *Thermodynamics*
It is science of the relationship
between heat , work , temperature and
energy .In broad terms,
thermodynamics deals with the
transfer of energy from one place to
another and from one form to another
.Also it has 4 laws :~ Zeroth law ,First
law, Second law and Third law of
thermodynamics.

4. *thermoelectriceffect*
It is the direction conversion of
temperature differences to electric
voltage and vice versa via a
thermocouple. A thermoelectric device
creates a voltage when there is a
different temperature on each side.

6. Applications of thermodynamics
All the refrigerators ,deep freezers ,
industrial refrigeration systems, all types
of air conditioning systems , heat pumps
etc. work on the basis of second law of
thermodynamics. All types of air and gas
compressors ,blowers, fans etc. run on
various thermodynamic cycles.

8. Applicationsof thermoelectriceffect
This effect can be used to generate
electricity, measure temperature or
change the temperature of objects.
Because the heating and cooling is
affected by the applied voltage,
thermoelectric devices can be used
as temperature controllers.
