What does diffusivity mean?
The measure of how easily a substance diffuses through a medium, such as a gas or a liquid. It is a measure of the rate at which particles move from an area of high concentration to an area of low concentration.
Example
"The diffusivity of the gas in the air was measured to determine its rate of spread."
