Atoms and molecules, introduction to the kinetic theory of gases, ideal gas. Pressure and temperature. Phases of matter, phase transitions and phase diagrams. Energy conservation and the first law of thermodynamics. Work, heat and internal energy in open and closed systems. Irreversible processes, entropy and the second law of thermodynamics. Cyclic processes, heat engines, refrigerators and heat pumps. Thermodynamic potentials and Maxwell's relations. The Clausius-Clapeyron equation. Fluid properties, surface tension and viscosity. Fluid statics, buoyancy. Fluid kinematics, momentum and power in fluid flow. Stationary incompressible flow.

Learning outcome

After having completed this course the student should be able to:

  • Understand qualitatively the connection between macroscopic properties of matter and the microscopic dynamics of atoms and molecules.
  • Use phase diagrams for pure substances.
  • Analyze simple open and closed systems using the first and second law of thermodynamics, continuity equation, impulse-momentum theorem and equations of motion.
  • Understand the basic properties of fluids such as surface tension, buoyancy, viscosity, laminar and turbulent flow.
  • Analyze simple flow problems using the energy and momentum equations.

Coursework requirements

Compulsory assignments (4 assignments), 2 obligatory hand-ins
  • The lab part consists of 4 tasks worked out individually.
  • Each studentattends one 3-hour lab session.
  • The lab sessions take place during one week in the second half of the semester.
  • Attendance in the lab is obligatory.
  • Lab reports are worked out in a python notebook and handed in individually.

The 2 obligatory hand-ins are to be delivered in the first half of the semester. These must be submitted within a given deadline and approved by the teacher. The approval will be only valid for two years.

Course assessment

There must be an early dialogue between the course supervisor, the student union representative and the students. The purpose is feedback from the students for changes and adjustments in the course for the current semester.In addition, a digital subject evaluation must be carried out at least every three years. Its purpose is to gather the students experiences with the course.
