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.”
![“[A]s you partake of the world's bill of fare, that's darned good advice to follow. Do a lot of spitting out the hot air. And be careful what you swallow.” quote by Dr. Seuss](https://sms4smile.com/quotes/img-quotes/da8/dr-seuss-1224_advice_a-s-you-partake-of-the-world-s-bill-of-f_6806.jpg)
