    Assessment methods

    The assessment will consist of an oral exam. The student will be asked to discuss about thermodynamics, heat transfer and environmental techniques. One question will consist on a simple exercise already discussed during the lectures. Una tantum, written exam at the end of the course for those who attend regularly the course. The final grade will be the sum between: clarity during exposition (up to 10);  knowledge of the arguments (up to 10); precision during the exposition (up to 10)
