We revisit thermodynamics and discuss 6 thermodynamics processes. What is an ideal gas? What's the difference between hyperbaric, isobaric, and hypobaric? What are the uses of idealized thermodynamics processes in the real world? We describe what happens to a piston in thermodynamic terms. What is the scientific definition of work? Should you call your refrigerator an isothermal system in front of friends? Is David Bowie exempt from the laws of physics?
