Consider the following biomaterials dispersed in water: Adenosine 5-triphosphate, abbreviated (ATP) with a diameter of 14 SARS-CoV-2 virus with a diameter of 100 nm At a temperature of 25C, the dynamic viscosity of water is 0.89 mPas and of air 18.5 Pas. a) What are the diffusion coefficients of these biomaterials in water and air at 25C? b) Based on the calculated diffusion coefficient, how relevant is the diffusive transport of viruses in air to disease propagation?
