Dr C.D.H. Williams
Delivery Weeks: T2:01-11
Level: 4 (NQF)
Credits: 15 NICATS / 7.5 ECTS
Enrolment: 144 students (approx)


Understanding properties of matter is both a basic aspect of physics and very important in view of its increasing technological importance. The coverage of condensed matter within the degree programmes is spread over a number of modules, this being the first. The aim of this module is to develop a sound understanding of the basic concepts of properties of matter. This is done at two levels. Topics such as elastic properties and hydrostatic properties are explained using experimental observations and macroscopic (large-scale) theories. Surface tension in liquids is explained using a molecular-level theory. This is followed by the a microscopic treatment of interatomic interactions, the ground-state electronic structure of atoms, and rotational and vibrational energy levels in molecules. The structure of liquid crystals is discussed in terms of different molecular arrangements. Finally, atomic structure and bonding in crystals with diamond structures and sodium chloride structures is described.
