Question

In reference to the figure, answer the following questions:

1. What does the figure illustrate?
2. Explain the temperature changes observed in two objects.
3. Write the principle behind this concept.

Answer 1

1. The figure illustrates the concept of heat exchange between a hot and cold object kept in an insulated box.
2. If heat is exchanged between a hot and cold object, the temperature of the cold object goes on increasing due to the gain of energy and the temperature of the hot object goes on decreasing due to the loss of energy.
3. Heat energy lost by the hot object = Heat energy gained by the cold object.
