Learning Objectives
Aim of the course is to give an operative and reasoned knowledge of Physics which could constitute a concrete support for Chemical studies.
Prerequisites
Courses required: none
Courses recommended: none
Teaching Methods
Total number of hours for Lectures (hours): 48
Type of Assessment
Oral and written tests. The written test is evaluated with a letter (A, B, C, D, E). To be admitted to the oral test it is necessary to receive an evaluation greater than or equal to D;
This admission, if not used, decays after 12 months or in case of changing of the teacher. The oral test consists in an argument decided by the student and carries to an evaluation in thirtieths. Eight exam sessions per year are foreseen.
