About this Chapter

This chapter forms part of Volume 3 (General Science) of the pareeksha.in exam-preparation series and covers two closely related branches of physics that are heavily tested in SSC (CGL, CHSL, MTS, GD Constable) and Railway (RRB NTPC, Group D, ALP) examinations: Heat (Thermal Physics) and Sound (Acoustics). Both topics are conceptual and formula-light compared to Mechanics, which makes them high-scoring if the underlying ideas are understood clearly rather than memorised mechanically. The notes below combine explanatory textbook-style prose with quick-reference tables so that the material can be used both for first-time learning and for rapid revision before the exam.
