diffusion coefficient
[dɪˈfjuːʒən ˈkoʊɪfɪʃənt]
nounpl: diffusion coefficients
coeficiente de difusão
1. A proportionality constant in Fick's law of diffusion that quantifies the rate at which molecules or particles spread through a medium
The diffusion coefficient determines how quickly a solute disperses in a solvent.
O coeficiente de difusão determina a rapidez com que um soluto se dispersa em um solvente.
2. A physical parameter used in chemistry and physics to describe molecular transport and concentration gradients
Scientists measured the diffusion coefficient of oxygen in water at different temperatures.
Os cientistas mediram o coeficiente de difusão do oxigênio em água em diferentes temperaturas.
3. In material science, a measure of the mobility of atoms or molecules within a solid, liquid, or gas
Higher diffusion coefficients indicate faster atomic movement in the crystal lattice.
Maiores coeficientes de difusão indicam movimento atômico mais rápido na rede cristalina.
This is a technical scientific term used uniformly in academic and industrial contexts across both Brazilian Portuguese and American English scientific communities. The terminology is standardized in chemistry, physics, and materials science textbooks worldwide.
