# BSc Physics with Theoretical Physics

Year of entry: 2021

## Course unit details:Properties of Matter

Unit code PHYS10352 10 Level 1 Semester 2 Department of Physics & Astronomy No

### Overview

Properties of Matter

### Aims

1. To show how the properties of macroscopic bodies can be derived from the knowledge that matter is made up from atoms.
2. To develop the ideas of classical thermodynamics.

### Learning outcomes

This course unit detail provides the framework for delivery in 20/21 and may be subject to change due to any additional Covid-19 impact.  Please see Blackboard / course unit related emails for any further updates

On completion successful students will be able to:

1. Describe and explain the first and second laws of thermodynamics, and the concept of entropy;

2. Define and derive the fundamental thermodynamic relation;

3. Use the formalism of thermodynamics and apply it to simple systems in thermal equilibrium;

4. Describe techniques for finding appropriate averages to predict macroscopic behaviour;

5. Apply these techniques to the calculation of the properties of matter.

### Syllabus
