Notes
This course covers the physical properties of matter -gases, liquids and solids. It explores the theory of gases, hydrostatics, properties of surface, elasticity, viscosity and fluid mechanics. Then in the second part of the course the concept of entropy and its statistical interpretation is introduced and Boltzmann's equation is derived. Building on this foundation, the laws of thermodynamics are explained and the topics of heat capacity, heat engines, thermodynamic potentials, Maxwell relations, chemical potentials batteries and fuel cells are explored. This course includes a project in which students work together in groups and will form part of the assessment.
Overview
The course content reflects the learning outcomes:
- Kinetic theory (simple kinetic theory of gases, sedimentation and the Boltzmann equation).
- Simple models of heat energy in solids (phonons).
- Heat capacity of solids, liquids and gases.
- Properties of surfaces (the Lennard-Jones potential, bubbles, surfactants).
- Elasticity (stress and strain tensors).
- Fluid flow, the Navier-Stokes equation and applications (e.g. flow through a pipe).
- Viscoelasticity (behaviour of viscoelastic systems under continuous and periodic driving forces).
- The laws of thermodynamics and their application (e.g. application to heat engines).
- Understanding the concept of entropy and its statistical meaning.
- Using thermodynamic concepts to solve problems - e.g. deriving potentials and reactions in cells and fuel cells.
Structure
Three lectures per week with sections ending in tutorials.
Assessment
One two hour examination (75%) two class tests (15%) one project (10%).
Same as above with continuous assessment carried forward.
Only the marks obtained at the first attempt can count towards Honours classification.
Formative Assessment
Dialogue with lecturer and problem classes at the end of each section.
Feedback
On the problem classes (immediately) and class tests (within one week).
