This online course deals with an introduction to the most powerful engineering principles you will ever learn - Thermodynamics: the science of transferring energy from one place or form to another place or form. Thermodynamics is a branch of physics that deals with heat and temperature, and their relation to energy, work, radiation, and properties of matter. The behaviour of these quantities is governed by the four laws of thermodynamics. It applies to a wide range of fields in engineering, such as chemical and mechanical engineering. By end of this module, students will be able to understand the basic thermodynamic principles widely used in different engineering fields and the tools which are required to analyze energy systems from solar panels, to engines, to insulated coffee mugs, etc.
