 Enable the students to understand the connection between the macroscopic observations of
physical systems and microscopic behaviour of atoms and molecule through a brief
knowledge of statistical mechanics.
 It also includes a basic idea about thekinetic theory of gases, transport phenomena
involved in ideal gases, phase transitions andbehaviour of real gases.
 The students will be able to apply these concepts to several problems on heat.
 The lab course deals with providing the knowledge of the concepts ofthermodynamics
along with Planck‘s law and Stefan Boltzmann laws related to black body radiation studied
in the theory paper with the help of experiments and give thestudents a hands-on
experience on the construction and use of specific measurementinstruments and
experimental apparatuses used in the Thermal Physics lab, including necessary
precautions.

LEARNING OUTCOMES:

At the end of this course, students will be able to
 Comprehend the basic concepts of thermodynamics, the first and the second law of
thermodynamics.
 Understand the concept of reversibility, irreversibility and entropy.
 Understand various thermodynamic potentials and their physical significance with respect
to different thermodynamic systems and processes.
 Deduce Maxwell‘s thermodynamical relations and use them for solving various problems
in Thermodynamics.
 Understand the concept and behaviour of ideal and real gases.
 Apply the basic concept of kinetic theory of gases in deriving Maxwell-
Boltzmanndistribution law and its applications.
 Understand mean free path and molecular collisions in viscosity, thermal conductivity,
diffusion and Brownian motion.
 Learn about the black body radiations, Stefan- Boltzmann‘s law, Rayleigh-Jean‘s law and
Planck‘s law and their significances.
 Gain the basic knowledge about quantum statistics: the Bose-Einstein statistics and the
Fermi-Dirac statistics.
 While doing the practical, the students will have an opportunity to understand and hence
use the specific apparatus required to study various concepts of thermodynamics. Hence,
the student will be able to comprehend the errors they can encounter while performing the
experiment and how to estimate them.
