Science and Technology I → Heat → Principle of Heat Exchange
·
Moderate
Add
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?
