(iii) Read the following paragraph and answer the questions :
If heat is exchanged between a hot and cold object, the temperature
of the cold object goes on increasing due to gain of energy and
temperature of the hot object goes on decreasing due to loss of
energy.

The change in temperature continues till the temperatures of both
the objects attain the same value. In the process, the cold object
gains heat energy and the hot object loses heat energy. If the
system of both objects is isolated from environment by keeping it
inside a heat resistant box, then no energy can flow from inside
the box or come into the box.

(a) Heat is transferred from where to where ?

(b) Which principle do we learn from this process ?

(c) How will you state the principle briefly ?

(iv) Draw a neat labelled diagram of electric motor and write its
principle.
