Air Quote by Wolfgang Ketterle
“When air is hot, the molecules move fast and they have high kinetic energy. The colder the molecules are, the smaller their velocities are and, subsequently, their energy. Temperature is simply a way to characterize the energy of a system.”
About This Quote
Source Lecture: Physics of Thermodynamics, 2015
Temperature reflects average kinetic energy of particles; hotter means faster, more energetic molecules.
In simple terms: Hot air = fast, energetic molecules; cold air = slow, less energetic.
