F.Y.B.Sc. | Sem II | PHY-121
Heat and Thermodynamics

We are very happy to hand over this text book of F.Y.B.Sc. Heat and Thermodynamics to F.Y.B.Sc. students. This book has been presented to you according to the revised syllabus of Savitribai Phule Pune University implemented from June 2019.
An attempt is made to give more emphasis on essential modern concepts in physics. The concepts are illustrated and elaborated with necessary examples. Sufficient exercise is given at the end of each of each topic for the practice of the students.
