SELT Survey Results

Thermal physics deals with large numbers of particles, anything big enough to see with a conventional microscope. From understanding the greenhouse effect to the blackbody radiation left over from the Big Bang, no other physical theory is used more widely throughout science.

This course provides an introduction to classical thermodynamics, with applications in materials science & engineering and earth science, as well as statistical thermodynamics, with applications in solid state physics and astrophysics.

The course begins with classical thermodynamics to introduce the fundamental concepts of temperature, energy, and heat. It then moves to statistical mechanics in which the laws of statistics are used to predict the behaviour of ensembles of particles through the concept of entropy. These concepts are then used within thermodynamics to explore free energies, and understand heat engines, refrigerators and phase transformations and fuel cells. The course then returns to statistical physics to where Boltzmann and Gibbs factors and partition functions are applied to both classical and quantum systems, including blackbody radiation and Fermi gases.

HPO is available for this course and will be worth 15% of the overall mark. Students can opt in to the HPO via the course Wattle page by Friday week 2. Students who do not submit HPO assessment or score lower in the HPO assessment, are considered to have opted out. See "other information section" for details.

Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

  1. Identify and describe the statistical nature of concepts and laws in thermodynamics, in particular: entropy, temperature, chemical potential, free energies, partition functions.
  2. Apply the statistical physics methods, such as Boltzmann distribution, Gibbs distribution, Fermi-Dirac and Bose-Einstein distributions to solve problems in some physical systems.
  3. Apply the concepts and laws of thermodynamics to solve problems in thermodynamic systems such as gases, heat engines, fuel cells and refrigerators.
  4. Analyze phase equilibrium condition and identify types of phase transitions of physical systems.
  5. Make connections between applications of general statistical theory in various branches of physics.
  6. Design, set up, and carry out experiments; analyse data recognising and accounting for errors; and compare with theoretical predictions.

Academic Integrity

Academic integrity is a core part of the ANU culture as a community of scholars. The University’s students are an integral part of that community. The academic integrity principle commits all students to engage in academic work in ways that are consistent with, and actively support, academic integrity, and to uphold this commitment by behaving honestly, responsibly and ethically, and with respect and fairness, in scholarly practice.

The University expects all staff and students to be familiar with the academic integrity principle, the Academic Integrity Rule 2021, the Policy: Student Academic Integrity and Procedure: Student Academic Integrity, and to uphold high standards of academic integrity to ensure the quality and value of our qualifications.

The Academic Integrity Rule 2021 is a legal document that the University uses to promote academic integrity, and manage breaches of the academic integrity principle. The Policy and Procedure support the Rule by outlining overarching principles, responsibilities and processes. The Academic Integrity Rule 2021 commences on 1 December 2021 and applies to courses commencing on or after that date, as well as to research conduct occurring on or after that date. Prior to this, the Academic Misconduct Rule 2015 applies.


The University commits to assisting all students to understand how to engage in academic work in ways that are consistent with, and actively support academic integrity. All coursework students must complete the online Academic Integrity Module (Epigeum), and Higher Degree Research (HDR) students are required to complete research integrity training. The Academic Integrity website provides information about services available to assist students with their assignments, examinations and other learning activities, as well as understanding and upholding academic integrity.

Online Submission

You will be required to electronically sign a declaration as part of the submission of your assignment. Please keep a copy of the assignment for your records. Unless an exemption has been approved by the Associate Dean (Education) submission must be through Turnitin.

All assessable items must be submitted through the Wattle site. Submissions emailed to convenor/tutors cannot be accepted.

Hardcopy Submission

For some forms of assessment (hand written assignments, art works, laboratory notes, etc.) hard copy submission is appropriate when approved by the Associate Dean (Education). Hard copy submissions must utilise the Assignment Cover Sheet. Please keep a copy of tasks completed for your records.

In Phys2020, no hardcopy submissions are permissible.

Late Submission

Late submission of the project report without an extension is penalised at the rate of 5% of the possible marks available per working day or part thereof. Late submission of project report is not accepted after 10 working days after the due date. Late submission is not accepted for quiz or homework assessments.

Referencing Requirements

The Academic Skills website has information to assist you with your writing and assessments. The website includes information about Academic Integrity including referencing requirements for different disciplines. There is also information on Plagiarism and different ways to use source material.

Returning Assignments

All feedback, including personalised marking of the project report and homework, is returned to the student through the Course Wattle grade book.

Extensions and Penalties

Extensions and late submission of assessment pieces are covered by the Student Assessment (Coursework) Policy and Procedure. Extensions may be granted for assessment pieces that are not examinations or take-home examinations. If you need an extension, you must request an extension in writing on or before the due date. If you have documented and appropriate medical evidence that demonstrates you were not able to request an extension on or before the due date, you may be able to request it after the due date.
