Aim

• The aim with the course is to introduce the classical thermodynamics for the students and also to exercise the students to use the different models presented in the course.

.

Knowledge and understanding
For a passing grade the student must

• know the first and second laws of thermodynamics and be able to calculate energy and entropy changes for temperature, volume and pressure changes.

• know the definitions of free energy and chemical potential and be able to use them for equilibrium calculations.

• know the thermodynamics of simple mixtures-mainly ideal solutions, but also simple models for nonideal systems. Be able to use activities and activity cofficients.

• be able to predict different colligative properties of a solution, such as osmotic pressure, freezing point depression and boiling point elevation, from the knowledge of the composition of the studied system.

• be able to use phase diagrams for two component systems

• understand the background to the equilibrium equation for a chemical system and

Skills and abilities
For a passing grade the student must

• be able to calculate pressure, volume and temperature in ideal and nonideal gases.

• be able to determine the temperature and pressure dependence of the different phase equilibria in a one component system.

• be able to calculate the vapour pressur and boling point of a two component solution.

• be able to calculate the temperature and pressure dependence of equilibrium constants.

• be able to use a numerical calculator to solve equations and integrate and also to use the calculator in least square fits of experimental data to a polynom function.

Judgement and approach
For a passing grade the student must

• understand the validity of the models presented in the course.
