Course Outline
Course Description
This introductory course is meant for multidisciplinary students in the School of Science and Engineering. It deals with equilibrium properties of macroscopic systems. It gives a macroscopic view of the phenomena of energy transfer encountered in physics, chemistry, biology, etc. , in the form of fundamental laws governing such a transfer, and the application of the laws. The course will base the teaching of the fundamental principles on thermal phenomena encountered in daily experience.
