NCERT Grade 11, Part 2, Physics Chapter 11, Thermal Properties of Matter is about the effects of temperature and heat on matter. In this chapter, you will learn what heat is and how it is measured and study the various processes by which heat flows from one body to another. Along the way, you will find out why blacksmiths heat the iron ring before fitting on the rim of a wooden wheel of a horse cart and why the wind at the beach often reverses direction after the sun goes down. You will also learn what happens when water boils or freezes, and its temperature does not change during these processes even though a great deal of heat is flowing into or out of it.
Measurement of Temperature through graphical representation, Ideal-Gas equation and absolute temperature, thermal expansion that deals with linear and volume expansion, thermal stress, specific heat capacity, calorimetry and working of a calorimeter, change of state and latent heat are concepts associated with heat and temperature in this chapter. Similarly, the students will learn about heat transfer and modes of heat transfer i.e. conduction, convection and radiation through mathematical expressions and also solve numerical problems based on them. The chapter will conclude with environmental awareness by discussing the greenhouse effect and Newton’s law of cooling. NCERT Grade 11, Part 2, Physics Chapter 11, Thermal Properties of Matter, is a part of Unit VII, Properties of Bulk Matter and hold a weightage of 20 marks including Unit VIII and IX.
