Solution


  1. 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.
  2. Principle of heat exchange can show that the energy exchange takes place between two objects only when kept in isolated system.
