Thermodynamics
In thermodynamics you remember the laws, gas laws, units and definitions of state quantities. Lumi has you recall them so you stop confusing heat, energy and temperature.

How to turn this subject into cards
Thermodynamics is full of quantities that look alike. Make one card set per quantity (temperature, heat, internal energy, enthalpy, entropy) with its definition, unit and an example. Add one card per law and one for the usual processes, isothermal, isobaric, isochoric, adiabatic. The typical trap is confusing heat and temperature, or forgetting the sign convention for heat and work. Lumi has you restate the convention before each exercise. Once a fact was known, retesting it had a large benefit on later recall in a vocabulary study (Karpicke and Roediger, 2008). It helps you remember definitions, laws, formulas and units.

The first law of thermodynamics says energy is conserved. The second law says the entropy of an isolated system never decreases. The ideal gas law is PV equals nRT. Absolute zero is minus 273.15 degrees Celsius. Heat flows spontaneously from hot to cold.
