Happy PChem-ing! email: lytica.pchem[at]gmail.com <video> Three-State Laser Description: The population inversion needed for a laser can't be achieved with just two electronic states. But with three states, the system can be pumped up to an upper state, in order to maintain a population inversion relative to an intermediate state. </video> <video> Adiabatic Flame Temperature Description: The enthalpy of combusion can be used to estimate the temperature at which a flame will burn. </video> <video> Heat Pump Description: A heat pump is the opposite of a heat engine. Rather than obtaining useful work as heat flows "downhill" from hot to cold, a heat pump uses work as an input in order to pump heat "uphill" from cold to hot. </video> <video> Particle on a Ring Description: The 1D particle-in-a-box model describes a particle confined to move along a line. When the particle is instead confined to a circle, its behavior is different, and can be described with the particle-on-a-ring model. </video> <video> Heat Engine Description: A heat engine makes use of the natural tendency of heat to flow from hot to cold, and converts some of that heat to work. The efficiency of a heat engine describes what fraction of that input heat can be converted to work. </video> <video> What is Physical Chemistry? Description: What topics fall under the category of physical chemistry, and what do they have in common? </video> <video> Carnot Theorem Description: The Carnot Theorem states that the efficiency of any reversible heat engine operating between a pair of temperatures is the same. It depends only on the two temperatures, and not on the type of heat engine, or the substances involved. </video> <video> Introduction Description: This channel contains short videos covering the entire scope of a two-semester undergraduate physical chemistry course. Here are my tips for how to learn physical chemistry by watching videos, along with some discussion of the features of these particular videos. </video> <video> Boltzmann-First PChem Description: The topics in physical chemistry are fairly standard, but the order in which they are presented varies a lot from one course or textbook to another. With a "Boltzmann-first" approach, paying a little extra attention to the Boltzmann distribution at the start allows many other topics to be introduced in a very natural way. </video> <video> Carnot Cycle Description: A sequence of isothermal and adabatic expansions and compressions of an ideal gas, called the Carnot Cycle, provides a way to turn heat into work. </video> <video> He-Ne Laser Description: A helium-neon laser takes advantage of the similarity in energy between an excited state of He gas and a different state for Ne gas. The He is pumped into the excited state, and the lasing transition occurs in the Ne, emitting red light of 633 nm. </video> <video> Lattice Models (Energy Transfer) Description: Lattice models can be used not only for the position of molecules, but also for their energies. </video> <video> Lightboard - Behind the Scenes Description: These videos are recorded using a lightboard. The image is digitally reversed so that you can read what I'm writing on the back side of the glass. </video> <video> Lasers (Basics) Description: A laser differs from an ordinary light source: the photons in a laser light source are monochromatic, collimated, and coherent. </video> <video> Air Pressure at Altitude Description: The Boltzmann distribution can be used to calculate how the air pressure drops with altitude. </video>
