ואם בשירים עסקינן
הנה שיר די ישן על החוק הראשון והשני של התרמודינמיקה: The First Law of Thermodynamics: Heat is work and work is heat. Heat is work and work is heat Very good! The Second Law of Thermodynamics: Heat cannot of itself pass from one body to a hotter body, Heat cannot of itself pass from one body to a hotter body Heat won´t pass from a cooler to a hotter, Heat won´t pass from a cooler to a hotter You can try it if you like but you´d far better notter, You can try it if you like but you´d far better notter ´Cos the cold in the cooler will get hotter as a ruler, ´Cos the cold in the cooler will get hotter as a ruler ´Cos the hotter body´s heat will pass to the cooler, ´Cos the hotter body´s heat will pass to the cooler Good, First Law: Heat is work and work is heat and work is heat and heat is work Heat will pass by conduction, Heat will pass by conduction And heat will pass by convection, Heat will pass by convection And heat will pass by radiation, Heat will pass by radiation And that´s a physical law. Heat is work and work´s a curse, And all the heat in the universe, Is gonna cooooool down ´Cos it can´t increase, Then there´ll be no more work And there´ll be perfect peace Really? Yeah, that´s entropy, maan! And its all because of the Second Law of Thermodynamics, which lays down: That you can´t pass heat from a cooler to a hotter, Try it if you like but you far better notter, ´Cos the cold in the cooler will get hotter as a ruler, ´Cos the hotter body´s heat will pass to the cooler. Oh you can´t pass heat, cooler to a hotter, Try it if you like but you´ll only look a fooler ´Cos the cold in the cooler will get hotter as a ruler And that´s a physical Law! Oh, I´m hot! Hot? That´s because you´ve been working! Oh, Beatles - nothing! That´s the First and Second Law of Thermodynamics! Author:Flanders & Swann From "At the Drop of Another Hat"
