FIS/01 - EXPERIMENTAL PHYSICS
II sem. dal Mar 1, 2017 al Jun 9, 2017.
Aim of this course is to introduce the basic concepts of the Special Theory of Relativity and of Quantum Mechanics and their application to Atomic and Nuclear Physics, to enable students to project and develop teaching activities on these subjects at high-school.
A part of the course will also be devoted to cover basic and advanced concepts of Thermodynamics.
Students should have knowledge of the status of Physics at the end of the 19th century, namely Newton’s laws of motion and theory of universal gravitation, laws of electricity and magnetism as described by Maxwell equations, theory and properties of electromagnetic waves.
- the Zeroth law: thermal and thermodynamic equilibrium; thermodynamic processes; empirical temperature; temperature scales
- the First law: work, heat,internal energy
- the Second law: Kelvin-Planck and Clausius statements; equivalence of Kelvin-Planck and Clausius statements; Carnot’s theorem; Carnot cycle; absolute thermodynamic temperature; Clausius theorem; entropy and energy degradation
