When you smell the aroma of freshly ground coffee, it indicates that it is deteriorating and the essence of coffee is decreasing.
If the diameter of coffee powder is doubled, the volume of individual particles is reduced by 1/8, and the surface area of the total coffee powder is doubled accordingly.
