Heating some molecules, particularly large, biological molecules such as proteins or nucleic acids, will cause them to change shape or even to break up.
The air comes through the diffusers in much larger velocities and different temperatures than the ones tolerated in the space. Due to diffusion, the velocity and the temperature differences are gradually decreased until they reach the tolerable limits.
The same principles that loft a 618-ton Airbus into the sky also keep a Formula 1 race car glued to the track. Downforce is lift inverted, the net result of the pressure differential between the air flowing over and under a front splitter, a front or rear wing, or an entire car body. In a modern Formula 1 car, the diffuser can contribute more than 1000 pounds of downforce. The problem is that this extra stick also raises aerodynamic drag, so engineers have to balance their need for cornering grip and stability against their carâs targeted maximum velocity.
