NCERT Grade 11 Physics Unit VIII includes Chapter 12, Thermodynamics. In this chapter, laws that govern thermal energy and processes where work is converted to heat and vice-versa will be studied by the students. Thermodynamics is the branch of physics that deals with the concepts of heat and temperature and the inter-conversion of heat and other forms of energy. Thermodynamics is a macroscopic science. It deals with bulk systems and does not go into the molecular constitution of matter.
Study of thermal equilibrium, zeroth law of thermodynamics, heat, internal energy and work, first law of thermodynamics, specific heat capacity, thermodynamic state variables and equation of state, thermodynamic processes, quasi-static process, isothermal process, adiabatic process, isochoric process, isobaric process, cyclic process, heat engines, refrigerators and heat pumps, second law of thermodynamics, reversible and irreversible, processes, carnot engine will be done through this chapter. Work by pioneers of thermodynamics, Lord Kelvin and Rudolf Clausius is mentioned in the chapter to understand the evolutions in the diverse filed of thermodynamics. Also, diagrammatic representation of processes and machineries involved in the learning of thermodynamics provides a realistic feeling to understand this physical phenomenon.
Laws, formulas, derivations and mathematical expressions are provided in a detailed and easy language for better understanding. Problem sums based on processes provides the students the logical sense of learning the concepts.NCERT Grade 11 Chapter 12, Thermodynamics along with chapters of Unit VII and Unit IX have 20 marks of weightage in the final examination.
