## Course unit details:Properties of Matter

Unit code PHYS10352 10 Level 1 Semester 2 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

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

1. Thermodynamics
The First Law: heat, work and internal energy. Functions of state. Reversibility
The Second Law: from heat engines to entropy.
Phase transitions: Gibbs Free energy, Clausius-Clapeyron equation, examples of phase transitions including Van der Waals gas.

2. Solids and liquids
Interactions between atoms: interatomic potentials and bonding.
Introduction to crystal structure and Bragg’s Law.
Elasticity; Young, shear and bulk moduli.
Bernoulli’s equation and incompressible fluid flow.
Liquid surfaces.
Drag: viscose and turbulent drag forces.

3. Kinetic theory of gases
Boltzmann factor.
Ideal gas equation and internal energy, including internal molecular modes.
Maxwell velocity distribution, mean speed.
Gas molecular collisions: mean free path.
Transport properties of gases; viscosity, thermal conductivity and self-diffusion.
