Question

(1) Read the following paragraph and answer the questions,
(5 marks)
Ans. If heat is exchanged between a hot object and a cold object.
the temperature of the cold object goes on increasing due to gain of
energy and the 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 this process, the cold object gains
heat energy and the hot object loses heat energy. If the system of both
the objects is isolated from the environment by keeping it inside a heat
resistant box (meaning that the energy exchange takes place between
the two objects only), then no energy can flow from inside the box or
come into the box.
Questions :
(1) Heat is transferred from where to where?
(2) Which principle do we learn about from this process?
(3) How will you state the principle briefly?
(4) Which property of the substance is measured using this
principle?​
