Learning outcomes
This course aims to give the students the knowledge of the basic concepts of the electromagnetism in empty space and the principles of thermodynamics, and how they can be expressed in mathematical form. The students have to reach knowledge of the scientific methods and of the natural laws so that they can solve problems in a quantitative form.

Teaching methods
Class lectures supported by PC slides. Exercises and problems sessions. Tutorial activity is foreseen.
Assessment methods
Written examination to be passed before the (compulsory) oral
examination.
The oral examination must be passed within 6 months from the passed
written one. If needed, more trials may be done within this period. The written exam consists in few problems and it typically lasts 90minutes. During the written exam the usage of a calculator and a formulary (provided by the professor) is allowed.The mark obtained following this examinations will be combined
with the one of the General Physics A part to give the final mark
for the General Physics course.
