Question
The cold object the hot object enclosed in one box of heat-resistant material.
- What changes will occur in the two objects when temperature flows from those objects?
- Which principle can show that the energy exchange takes place between two objects only when kept in isolated system?
Solution
1. Temperature of cold object increases due to gain of heat energy.
2. At the same time, temperature of hot object decreases due to loss of heat energy.
3. The process of heat exchange continues till both the objects acquire the same temperature.- Principle of heat exchange can show that the energy exchange takes place between two objects only when kept in isolated system.
