21. Thermodynamics

Fundamentals of Physics (PHYS 200) This is the first of a series of lectures on thermodynamics. The discussion begins with understanding "temperature." Zeroth's law is introduced and explained. Concepts such as "absolute zero" and "triple point of water" are defined. Measuring temperature through a number of instruments is addressed as well as the different scales of measurement. The second half of the lecture is devoted to heat and heat transfer. Concepts such as "convection" and "conduction" are explained thoroughly. 00:00 - Chapter 1.

23. The Second Law of Thermodynamics and Carnot's Engine

Fundamentals of Physics (PHYS 200) Why does a dropped egg that spatters on the floor not rise back to your hands even though no laws prohibit it? The answer to such irreversibility resides the Second Law of Thermodynamics which explained in this and the next lecture. The Carnot heat engine is discussed in detail to show how there is an upper limit to the efficiency of heat engines and how the concept of entropy arises from macroscopic considerations. 00:00 - Chapter 1.

Thermodynamic Temperature

www.facebook.com ... Physics (Episode 5): Thermodynamic Temperature. --- Please SUBSCRIBE to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com --- What is the temperature of outer space? way out there between galaxies ... where there is only about one hydrogen atom per cubic meter? Can an individual atom be hot or cold? Can it even have a temperature? It sounds a little silly to say an atom is 27 degrees Fahrenheit or something. PARTICLE TEMPERATURE: But temperature is really a measure of the motion energy of an atom if the atom is motionless then it is at zero Kelvin. Now it can never be really motionless so it can never be at exactly zero Kelvin. And it moves pretty fast pretty fast as the temperature rises. At a tiny fraction of a degree above absolute zero, (700 nK (1 nK = 10−9 K)) the atom is already moving at about 1 centimeter per second. For subatomic particles the energy is often measured in MeV or GeV. An electron with 1 GeV of energy is moving close to the speed of light. And that corresponds to a temperature of ... 11 thousand billion kelvins. AVERAGE TEMPERATURE: For a collection of atoms or molecules like a gas or a crystal lattice, the temperature of the collection is just the average temperature of the group. But of course because of collisions and interactions at the molecular level, a group of atoms or molecules will distribute the total motion energy pretty evenly among the individuals in the collection. HEATFLOW: And if two or ...

24. The Second Law of Thermodynamics (cont.) and Entropy

Fundamentals of Physics (PHYS 200) The focus of the lecture is the concept of entropy. Specific examples are given to calculate the entropy change for a number of different processes. Boltzmann's microscopic formula for entropy is introduced and used to explain irreversibility. 00:00 - Chapter 1. Review of the Carnot Engine 19:18 - Chapter 2. Calculating the Entropy Change 35:34 - Chapter 3. The Second Law of Thermodynamics as a Function of Entropy 43:46 - Chapter 4. The Microscopic Basis of Entropy Complete course materials are available at the Open Yale Courses website: open.yale.edu This course was recorded in Fall 2006.
