GRADING SYSTEM FOR THE COURSE

This course will be graded as follows:

Class Attendance 5%

Assignments 15%

Test(s) 20%

Final Examination 60%

TOTAL 100%

GENERAL INSTRUCTIONS

Attendance: It is expected that every student will be in class for lectures and also participate in all class exercises. Attendance records will be kept and used to determine each person’s qualification to sit for the final examination. In case of illness or other unavoidable cause of absence, the student must communicate as soon as possible with any of the instructors, indicating the reason for the absence.

Academic Integrity: Violations of academic integrity, including dishonesty in assignments, examinations, or other academic performances are prohibited. You are not allowed to make copies of another person’s work and submit it as your own; that is plagiarism. All cases of academic dishonesty will be reported to the University Management for appropriate sanctions in

accordance with the guidelines for handling students’ misconduct as spelt out in the Students’ Handbook.

Assignments and Group Work: Students are expected to submit assignments as scheduled through their course representative. Failure to submit an assignment as at when due will earn you zero for that assignment. Only under extenuating circumstances, for which a student has the instructor in advance, will late submission of assignments be permitted.

Code of Conduct in Lecture Rooms and Laboratories: Students should turn off their cell phones during lectures. Students are prohibited from engaging in other activities (such as texting, watching videos, etc.) during lectures. Food and drinks are not permitted in the lecture hall.

COURSE OUTLINE

Week Topic Remarks

1 Introduction and Course Overview- foundation of classical thermodynamics including Zeroth laws and definition of temperature;

During this first class, the expectation of the students from the course will be documented. The course will also review some of the familiar concepts related to the conservation of energy (the first law) as applied to thermodynamics. Quantities such as temperature, internal energy, work and heat will be introduced

2 & 3

Thermodynamics terms:

 Micro and macroscopic systems

 Quasi-statics systems

 Cyclic, Isochoric processes

First law of thermodynamics, work, heat and internal energy

The lecture will involve explanation of some thermodynamics terms and the first law of thermodynamics

4 & 5

Second law of thermodynamics

 Carnot cycle  Efficiency of a machine  Entropy  Reversible and irreversibility,  thermodynamic potentials; and  Maxwell relations,

When learning on thermodynamics systems, students will be taught on what laws of thermodynamics meant. In addition, precise relation between temperature and entropy will be given by considering interactions between two macroscopic systems

6 Applications of First and Second law of thermodynamics

Exercises will involve some simple applications on first and second law of thermodynamics. The first and second laws are then applied to the discussion of engines and refrigerators.

7 & 8 Qualitative discussion of phase transitions; Students will be taught on the phase transitions from solid to liquid and liquid to gas and equilibrium between states of matter and the thermodynamics processes that takes place during the transitions will be the next main topic

MID-SEMESTER TEST

9 & 10 Third law of thermodynamics, ideal and real gases and its applications

Students will be taught third law of thermodynamics and apply it to ideal and real gases

Scene 5 (4m 2s)

5

11 & 12 Elementary kinetic theory of gases including Boltzmann constant

Students will be taught on elementary kinetic theory and its principles

13 & 14  Maxwell-Boltzmann law of distribution of

velocities

 Simple applications of the distribution law

Maxwell –Boltzmann is a very powerful relation in thermodynamic theory. Students will be taught on how to derive the relation and apply it to distribution law. Finally, introduction to classical Boltzmann statistics and quantum statistics will wrap up the course

15 REVISION This is the week preceding the final examination. At this time, evaluation will be done to assess how far the students’ expectations for the course have been met.
