Talk About It

  1. 1.On the hot morning, the vents blew warm air. Where did Coda say the cool air is supposed to begin?
  2. 2."Make it, move it, clean it." Which machines make the air, and which parts move and clean it?
  3. 3.What does the thermostat do? Why did Coda call it "the boss of the air"?
  4. 4.Why does a hospital need its air kept clean and just right?
