What’s a conc. gradient?

[ad_1] Concentration gradients occur between areas of high and low concentration. Diffusion and osmosis move particles along or against gradients, while active transport mechanisms move particles against gradients. The concentration of a substance is the number of molecules present in a given volume of liquid or gas. A concentration gradient occurs between an area of […]

Temp gradient: what is it?

[ad_1] Temperature gradients are gradual changes in temperature with distance, measured in degrees per unit of distance. They exist naturally and can be created, but convection can destroy them. Insulation helps maintain them. The Earth has different temperature gradients in each layer. Maintaining constant gradients is important in some industrial processes and for optimal performance […]
