Thermodynamics
Physics 202, Lecture 6
1
The first law: a heat engine balances internal energy, heat and work
Physics 202, Lecture 6
2
The ideal gas provides the simplest system to consider in thermodynamics
Physics 202, Lecture 6
3
Work done by an ideal gas within isothermal and adiabatic process can becalculated
Physics 202, Lecture 6
4
The Carnot heat engine is reversible and is therefore the upper bound onefficiency
Physics 202, Lecture 6
5
Another perspective on entropy: energy irreversibly lost to mechanicalwork
Physics 202, Lecture 6
6
Any decrease in system entropy must come from a larger increase some-where else
Physics 202, Lecture 6
7
Practical questions about the most efficient use of global energy is chal-lenging
