| Part | Topics Covered | |------|----------------| | I: Heat | Thermometry, calorimetry, thermal expansion, heat transfer (conduction, convection, radiation). | | II: Thermodynamics | Zeroth, First, Second, and Third laws; Carnot cycle; entropy; thermodynamic potentials (Gibbs, Helmholtz); Maxwell’s relations. | | III: Statistical Physics | Kinetic theory of gases, partition function, classical statistics, quantum statistics, Bose-Einstein condensation, Fermi gas. | | Appendices | Mathematical tools (partial derivatives, gamma functions), physical constants, tables of specific heats. |
The book contains over 300 solved examples and 500 unsolved problems (with answers). Many of these problems appear verbatim in major university exams (Delhi University, Mumbai University, University of Calcutta, etc.).
You have the file. Now, do not just stare at it. Here is a 4-week study plan:
Week 1 & 2 (Thermodynamics): Focus on the Laws. Use the PDF’s search function to find every occurrence of "Carnot cycle." Solve the numerical problems at the end of Chapter 3 first—they are the easiest.
Week 3 (Kinetic Theory): Pay attention to the derivation of Pressure (P = 1/3 mnv^2). This is a favorite for exam short-notes.
Week 4 (Statistical Physics): This is where the Brijlal & Subramaniam book shines. Read the section on "Phase Space" slowly. Use highlighters in your PDF reader. The difference between MB, BE, and FD statistics is the heart of modern physics.
Pro Tip for Competitive Exams: Look up "Thermodynamic Potentials" (Chapter 4 in most editions). Draw the Maxwell square from memory. This single diagram can solve 5 marks in the JEST or TIFR exam.
