Answer the following questions

SCERT Maharashtra Question Bank solutions for 10th Standard SSC Science and Technology 1 Maharashtra State Board 2021 Chapter 5 Heat Answer the following questions

Answer the following questions | Q 1

Read the passage and answer the questions based on it.

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 the temperature of the hot object goes on decreasing due to loss of energy. The change in temperature continues till the temperatures of both 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 then no energy can flow from inside the box or come into the box. In this situation, we get the following principle.
Heat energy lost by the hot object = Heat energy gained by the cold object. This is called the ‘Principle of heat exchange’.

  1. Where does heat transfer take place?
  2. In such a situation which principle of heat do you perceive?
  3. How can this principle be explained in short?
  4. Which property of the substance is measured using this principle?
