Thermal Physics

Thermal Physics. Instructor: Prof. Debamalya Banerjee, Department of Physics, IIT Kharagpur. Thermal physics is a course that is designed to fulfill the requirements of first and second year BSc students studying physics. Starting from basic understanding, this course will take the students through all fundamental aspects of thermodynamics in a simple way. The first part of the course deals with the Kinetic theory of gasses, which bridges the connection between macroscopic and microscopic worlds. In here, we have also included transport phenomena involved in ideal gasses, the theory of specific heat and behavior of real gasses. In second half of the course, effort is made to understand the fundamental laws of thermodynamics and applications to various thermodynamic systems and processes.Additionally, a discussion on black body as a thermodynamic system has been included.
