Thermodynamics part 3: Kelvin scale and Ideal gas law example. Sal makes the case for the Kelvin scale of temperature and absolute zero by showing that temperature is proportional to kinetic energy. Then he explains that you need to use the Kelvin scale in the ideal gas law. To finish he does a sample ideal gas law problem. Created by Sal Khan. Temperature, kinetic theory, and the ideal gas law. Thermodynamics part 1: Molecular theory of gases. Thermodynamics part 2: Ideal gas law.
