Practical Physics by Dr. Bhasar Jyoti Hazarika is a comprehensive laboratory manual designed specifically for the B.Sc. 3rd Semester Physics Honours CBCS syllabus, with a strong focus on Thermal Physics Practical. This book serves as a complete guide for undergraduate students to build experimental skills, understand measurement techniques, and apply theoretical principles of thermodynamics and heat-related phenomena in the laboratory.

The manual blends conceptual clarity with hands-on learning, presenting each experiment in a structured, easy-to-follow format. Step-by-step procedures, clear diagrams, tabular formats for observations, calculation guidelines, error analysis, and viva-voce questions make it an ideal resource for both students and instructors.
