This video goes over the definitions of temperature, internal or thermal energy, and heat, and explains how each is different from the other and how all the definitions connect to the kinetic theory of matter. I explain how two objects with the same temperature can have different thermal energy, how cold objects can have more thermal energy than hot objects, temperature scales and units (Fahrenheit, Celsius, and Kelvin), absolute zero, heat transfer, and what the conservation of energy tells us about heat.
