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.
As particles move from concentrated areas, they diffuse throughout the liquid or gas to create an equilibrium, or even spacing. The rate of diffusion is dependent on three aspects: the temperature, the mass of the particles and the thickness of the liquid or gas. An increase in temperature creates more energy, so the particles move faster. Heavier particles require more energy to move; the higher the mass, the slower the movement.
